Thank you, Joe, and good afternoon. First quarter revenues came in well above our expectations, growing 58% from the first quarter of 2020.

This outsized growth rate reflects prevailing demand conditions in our industry but also our growing market share and the impact of secular trends that are expanding our addressable market and driving customers toward our highly integrated products.

These trends include energy efficiency, electrification, renewable energy, home and building automation, smart connector appliances, LED lighting, advanced mobile device chargers and the replacement of high-voltage silicon switches with gallium nitride.

We expect these tends to endure well beyond the current semiconductor cycle, and we are making the necessary investments in products, people, facilities, capacity and infrastructure to capitalize on the opportunities in front of us. One such investment is our newly redesigned power.com website, which was launched earlier this month.

The new website serves as an extension of our sales and applications engineering team putting our renowned PI expert design tool, front and center to let engineers tap into our watch reservoir of design know-how.

The size also better reflects our recent expansions into automotive and motor drive markets incorporates advanced authorization capabilities and features upgraded e-commerce functionality to enable customers to buy parts immediately from our distributors. Turning to Q1 results.

Revenues were $174 million, up 15% from the prior quarter and 58% year-over-year, demonstrating the leverage in our model, and our non-GAAP operating margin expanded to 28.6% and our non-GAAP EPS doubled year-over-year to $0.76.

Cash flow from operations was also very strong at $58 million All four end market categories exhibited strong year-over-year growth in the first quarter. Revenues from computer category nearly tripled from a year ago, driven by strong demand for tablets, PCs and monitors as well as penetration of fast chargers in the tablet market.

Revenues from communications category were up more than 170% year-over-year, driven by growth in handset market, share gains by our OEM customers, and most importantly, that the continuing adoption of advanced chargers and our success in capturing a large share of that market.

We have built a commanding lead in advanced chargers, thanks to our highly integrated invoice products, including our GaN-based InnoSwitch devices, which offers the highest level of efficiency in the market. Efficiency is essential in fast chargers because any heat resulting from wasted energy must be dissipated through the surface of the charger.

Mostly it requires more surface areas, which means that bigger charger, even worse, inefficient high-power chargers often require heat sinks, which add size, weight and cost. The efficiency of our InnoSwitch products helps solve these thermal challenges, enabling the smallest, lightest and fastest chargers on the market.

We won a broad range of new advanced charger designs in Q1, including OEM branded chargers as well as aftermarket designs from a proliferating number of brands. Many of these designs feature multiple charging ports and provide enough watts to power and load book while rapidly charging a phone or tablet.

We are seeing tremendous uptake of our GaN products in such designs. And as a result, we believe we are on track to grow our overall GaN revenues by at least three times this year.

Of particular note is a 65-watt USB PD charger using a GaN-based InnoSwitch alongside our GaN-based mini capture, which shrinks the charger by drastically reducing the size of the input capacitors.

This design, as you mentioned on the last quarter’s call was introduced earlier this week by a major OEM as the inbox adapter for the newest line of slim notebook computers. In its promotional video, the OEM prominently mentioned it’s use of GaN in the adopter to save energy, but also highlights the combined weight of the notebook and the adapter.

This is in contrast to the familiar experience in which we buy a notebook based on its advertised size and weight, only to find out that it comes with a huge clunky adapter.

Notably, the OEM is also offering this same adapter as a super fast charger for use with their cellphones, demonstrating the paradigm shift occurring in the mobile device market thanks to technologies like GaN and USB PD.

We believe this is just the beginning of the long-term trend toward advanced multi-use chargers with high-performance semiconductors and far higher dollar content than chargers of the past.

Continuing with the Q1 results, industrial revenues were up high teens year-over-year, driven by home automation and IoT applications as well as battery-powered tools, two of the fastest-growing verticals in our industrial category.

Consumer revenues grew in the low teens, driven by strong demand for appliances as well as continued share gains and rising dollar content. China’s new efficiency standards for air conditioners are also contributing to the growth in our consumer category.

Notably, we achieved double-digit growth in consumer despite a very strong first quarter last year that included panic buying in the early stages of the pandemic. Regarding the current demand environment, like most semiconductor companies, we have seen extremely high order rates in recent months.

Lead times have extended on many products, and we have experienced sharp reductions in inventories both in-house and in the distribution channel.

However, while not immune to the challenges of the current environment, we have mitigated them to a large extent, thanks to our decision to build inventory as demand softened in the early stages of the pandemic. Another cushion against the current demand shock is of a unique manufacturing model.

Our proprietary process technologies enable us to rely not on traditional merchant foundries, but rather on trailing edge facilities of vertically integrated suppliers.

We believe our long-term partnerships with such suppliers and our industry – our history of maintaining relatively steady production levels in periods of weaker demand helped to ensure that we have access to fab capacity when demand surges.

Similarly, we have been able to mitigate the tightness in back end capacity across the industry, thanks to the use of proprietary IT packages, our ownership of equipment used in manufacturing and testing of these packages and our substantial investment in new capacity over the past year.

Looking ahead, we continue to expect that demand will begin to normalize at some point in the coming quarters as the impact of work from home pickings to dissipate, appliance makers catch up with demand and the dislocation caused by Huawei sanctions plays out. However, in the near term, demand continues to be very strong.

We entered the second quarter with a record backlog and bookings have remained elevated throughout the month of April. Distribution sell-through far exceeded sell in again in the first quarter, and distributors ended the quarter with an unsustainably low level of inventory.

As a result, we expect our second quarter revenues to be flat compared to the first quarter, plus or minus 5%, and which at the midpoint would be up more than 60% year-over-year.

Looking further ahead, while some cellphone OEMs have likely overbuilt in an effort to capitalize on Huawei sanctions, our OEM customers have been major beneficiaries of the transition, which will magnify the share gains we have achieved through our success in advanced chargers.

More broadly, we believe we have gained share across a number of end markets over the past few quarters, which should benefit as well after the current cyclical noise of sites. Finally, on behalf of our Chairman, Bill George, I’d like to note the appointment of Jennifer Lloyd to our Board of Directors effective April 1.

As leader of a major business unit at analogue devices, Jennifer brings an exceptional combination of technical expertise and executive management experience to our Board as well as deep knowledge of analog semiconductor industry. We are delighted that she has joined our Board of Directors. And with that, I will turn it over to Sandeep..

Thank you, Balu, and good afternoon. As usual, I will focus my remarks primarily on the non-GAAP results, which are reconciled to GAAP in our press release tables. First quarter revenues were $174 million, up 15% sequentially with all four end market categories, up from the prior quarter.

Communication revenues increased more than 25%, driven by continued strength in advanced charges. Computer revenues were up low double digits, driven mainly by fasts chargers for tablets.

Industrial revenues were up low double digits sequentially, driven by broad-based industrial application as well as strength in metering, home and building automation and high power. Consumer revenues grew mid-single digits, driven by the broad-based strength in appliances, which comprise the bulk of our consumer category.

Revenue mix for the quarter was 38% communication, 29% consumer, 25% industrial and 8% computer. As expected, gross margin was sequentially lower, reflecting the greater percentage of revenues coming from the communication market. Non-GAAP gross margin was 49.4% for the quarter, down 70 basis points from the prior quarter.

I noted on last quarter’s call that we expect Q1 to be the low watermark in terms of gross margin, and I still expect that to be the case as we should see the benefits of manufacturing efficiencies over the next several quarters and possibly a more favorable end market mix in the second half of the year.

Non-GAAP operating expenses were $36.2 million for the quarter, down $1.8 million from the prior quarter and below our expectations, primarily reflecting the timing of hiring. Non-GAAP operating margin for the quarter was 28.6%.

The other income for the quarter was about $600,000, while the non-GAAP effective tax rate for the quarter was 7.1%, resulting in non-GAAP earnings of $46.7 million or $0.76 per diluted share. Cash and investments on the balance sheet rose by $42 million from the prior quarter, driven by strong free cash flow.

Cash flow from operations was $58 million, while capital expenditures were $11 million.

We paid out $7.8 million in dividends following the $0.02 increase that we announced last quarter, reflecting the strength of our balance sheet, our Board of Directors has allocated an additional $50 million to our share repurchase authorization, bringing the total to $91.3 million.

Internal inventories fell to 92 days, a decrease of 30 days from the prior quarter, while channel inventories fell to approximately two weeks as sell-through once again exceeded sell in. Looking ahead, we expect second quarter revenues to be flat compared to the first quarter, plus or minus 5%.

The gross margin should improve as the impact of manufacturing efficiencies begin to flow through the P&L. Specifically, I expect non-GAAP gross margin to be in the range of 50% to 50.5%. The operating expenses will increase sequentially in Q2, driven by annual merit increases, which took effect in early April as well as continued growth in headcount.

For the full year, I expect non-GAAP OpEx to increase by about 10%, coming off a flattish year in 2020. Other income for Q2 should remain at a similar level to March quarter, while the non-GAAP effective tax rate should also remain steady at around 7% to 8%. And now operator, let’s begin the Q&A..

[Operator Instructions] Our first question comes from the line of Karl Ackerman from Cowen. Your line is open. You may ask your question..

Thank you, and good afternoon gentlemen. First off, clearly, supply chain constraints have been pervasive across the semi supply chain. I know you are fab light, but I think you’ve been securing capacity at your Japanese foundry partners for the last few quarters.

I mean, given the very strong results in Q1 and for the outlook for June, I guess, at what revenue level are you able to service demand before needing to secure incremental capacity?.

Karl, thanks for the question. Right now, I believe we have enough capacity to meet the ongoing crew demand not enough to supply all the parts customers want to buy. And as you can imagine, customers are ordering way over what they need.

But we are trying to make sure that we keep all of the inventory in one place that’s with us rather than have individual customers build their inventory. At some point, they’ll have to but at this point, we are trying to manage that so that we can serve all customers well.

So we think for the rest of the year, that will be the case, unless something changes. And also, as we all know, the current booking rate is in excess of the normal run rate, thanks to work from home and learn from home demand. But there will be a time that will normalize. We don’t know exactly when it is, but it could be in the next few quarters.

Our expectation is the second half will be lower in revenue than the first half. And that’s because we believe it will start to normalize at some point. So given all of that, I don’t believe at the moment, we have a problem with our ability to take care of customers, but they’ll have to wait for a while to build inventory.

And that’s also true for distributors. We will try to build more inventory because two weeks is too low. But it will all depend upon what the true demand is..

I guess that dovetails on my second question, which is just getting a little bit better understanding of your view for gross margins next quarter, right? You just indicated that, hey, distributor lead times are quite low. At the same time, many peers across the supply chain have spoken about rising substrate and shipping costs.

And so I appreciate the outlook that you are giving for June, if I read between the lines, perhaps if due to a little bit less mix in mobile.

But I guess with many larger peers raising prices across the distribution channel and lead times extending, how are you thinking about volume versus price and the value that you are offering many of your customers.

And I guess, purely in volume, are you able to sign longer-term volume agreements with these customers going forward?.

I think the way to look at it is, yes, there are a lot of moving parts, whether it’s cost, whether it is the impact of foreign currency on a reduction the way I think the best to answer you, we provided guidance at the beginning of the year that our gross margin for the year would approximately be around 15%.

We still believe that with all the moving parts, we will still achieve the 50%.

And I’d also like to add that one of the reasons we feel confident about meeting the true demand is that we are, I believe, in a better position than most of our competitors so we will not be the long-haul in the tent because of the cautions we took, we built a lot of inventory. We have committed capacity from our fab partners.

And we are continuing to build additional capacity integration for growth next year. I think we are in much better shape than most other companies..

Thank you..

Thank you, sir. We do have another question from the line of Tore Svanberg from Stifel. Your line is open. You may ask your question..

Yes. Thank you and congratulations on the record results. Balu, when it comes to share gains, I guess in this environment, there’s several ways to gain that share. But you mentioned one of them, obviously, keeping your inventories high and the capacity.

But the other way, of course, is by having a more integrated solution, and when discretes are probably selling at very long lead times, I would guess that is also a good reason why you would gain share.

Could you comment a little bit on that? And would those have sort of equal weight on your ability to gain share?.

Thanks, Tore. Yes, you hit on several reasons are getting shares. The biggest one is we have by far the most attractive solution in terms of efficiency size and rate. In fact, if you want the smallest size adapter, there is no other place to go. You have to make that up a bigger power supply bigger to use somebody else’s solution. That’s number one.

And so we have been gaining share, independent of the current cycle, and that has continued through this cycle. But on top of that, you hit on the right point, because it’s hard to get the space components, we have a huge advantage because our solutions are half the components compared to our competitors. So they prefer our solution.

There are a couple of other things going on. As you know, our customers are gaining share from Huawei and so that kind of magnifies the share gains that we have. And on top of that, a number of our competitors are having trouble shipping products because they have they are prioritizing other areas like automotive to ship into.

So as a result, we are getting share gains. Sometimes because that are dual sourcing at the power supply level. But sometimes even otherwise, because what happens is that if they cannot get a particular type of charger because of our competitors having challenges, they a substitute our charger.

In some cases, they’ve gone from a 15-watt charger to 33-watt charger using our solution simply because the 15-watt charger, they cannot get components from China. China for that matter. So in some ways, it’s accelerating the migration of advanced fast chargers into lower end phones. So there are many, many reasons we are gaining share.

The good news is we believe a lot of this is permanent because once the shift is shared to us, they get used to the benefits they bring. So we are very, very thrilled that we are gaining so much share faster than we thought originally, thanks to the current cycle. In total, there are other areas like appliances where the standard changes happen.

And that change, there’s a switch from the variable frequency motors to the fixed frequency failure [ph] power supplies substituted with electronic power supply. And again, it’s an area where we have great products, and that is enabling us to gain further market share.

So the market share gains that we are talking on, we are seeing in all end applications. That’s the big switch that we are seeing right now, things coming our way..

That’s great perspective. My second question is on the channel inventory at two weeks. I mean, that’s the lowest I’ve ever seen.

And I think normalized is like seven to eight weeks, do you think that this ties will try and build back to that level? Or is there sort of a new norm or a new supply chain where that is not the number we should use going forward?.

No, no. The 1.9 weeks or two weeks is unsustainable. They just can’t serve the customers at those levels. My expectation is that could come up a couple of weeks in Q2. And that’s one of the reasons we think Q2 is going to be flat. If you remember, originally, we thought Q2 will be lower because of the strength we’ve had in Q4 and Q1.

But because of the low channel inventory, we now expect Q2 to be flat. So unless the demand the increases further, we expect some buildup in the channel inventory..

Great. And last question, you mentioned there’s a good chance that demand will be lower second half versus first half.

I assume that’s primarily associated with the communications market? Or would you say that applies for other segments as well?.

Well, it will apply for other segments, like computer and consumer markets. If you look at the demand, it looks like it’s all driven by work at home and learn from home situation right now. So people are buying more computers. They’re buying more appliances.

In fact, if you look at appliances right now, if you try to buy an appliance, you’ll have a hard time doing that. Whirlpool just announced that their backlog is now six to – five to six weeks to their retail chain. So the appliance in that is still pretty high.

And at some point, those demand will be satisfied, especially if we recover from COVID, at some point, it will have to normalize demand has to normalize. I don’t know whether normalization will occur in Q3, Q4 or Q1. Our best estimate is that the second half will be lower than first half.

Tore the other thing, if you remember, last year, we did a 16% growth. So as you know historically, we cease the upside sooner and then things turn and normalize, we will see that sooner. That’s why you’re seeing us talk about it in this way because things will normalize, and we tend to see that sooner..

Yes. I really appreciate the transparency there. Thank you so much..

Thanks Tore..

Thank you, sir. We do have another question from the line of Ross Seymore from Deutsche Bank. Your line is open. You may ask your question..

Hi guys, I guys want to echo to the other guys and things congress on the ridiculously strong results. It’s very impressive. I guess the first question is on the channel side, Balu, you talked about it refilling that has a little tailwind for the second quarter.

I guess first, there’s two ways if I blend the channel inventory comment and then the second half might be a little weaker, there’s two ways that the weeks of inventory can rise, do you believe that it will rise solely by you guys actually shipping more in the channel? Or are some of the orders and the bookings rates and revenues of your customers going to drop so that they will actually have more weeks of inventory on the same dollar amounts from you guys..

That’s a good question. I have no wares knowing. All I know is that it’s a very dynamic situation. Even though we have very strong bookings and very strong backlog we also see that the backlog gets adjusted in many different ways in terms of mix, in terms of push outs, pull-ins and so on. So I just feel that at some point, this has to normalize.

Whether it happens in Q2, I don’t know. I mean, looks pretty strong to us. That’s why we’re giving the guidance we are giving. But I am thinking that Q3 or Q4, there will be some normalization. It is hard to predict, but it’s just a gut feeling at this point..

Fair enough. I guess as my follow-up, and it might fall into the same gut feeling category, but the second half versus being below the first half. I think your logic makes tons of sense. And again, like Tory said, I appreciate your transparency on that most companies wouldn’t front run any potential bad news.

Any sort of magnitudes, you’ve said you have the ability to shift to what you deem to be real demand or true demand, but not all the bookings.

Any sort of color as far as what the delta is between those numbers, the magnitude, first half to second half, even roughly that you’re considering?.

Well, again, it will be pure speculation at this point. My feeling that Sandeep can add to it because we both always speculate on what’s going to happen. I believe it will be slightly lower than first half.

the reason we don’t ship to whatever customer wants is because that’s just going to cause more problems because you’ll end up building inventory at the customer, which means that the normalization will be more drastic sort to speak.

What we wanted is make sure we take care of our customers, keep all the inventory in one place, so that it will be more smoother in normalization than if they end up building a lot of inventory. The other reason we do that is that we can serve everybody better.

If the – if our inventory gets distributed among several customers, we have no way of getting it back in case somebody else who needs it badly either because they didn’t anticipate and the book ahead of time. And therefore, we had to be very careful that we don’t ship to customers who are overtaking the lower bookings simply because they’re panic.

They may be looking at multiple semiconductor companies. So is it a perfect situation? No, we have no way of absolutely knowing that we are not shipping into inventory. In some cases, we are much more confident, like in sales force because we know how many cellphones are sold from each it’s a lot harder.

It was fragmented like appliances and industrial markets. So we just have to work with the customer and hope that a customer cooperates with us and only it takes products that are needed to run the production, not build inventory at this time. Eventually, we’ll have to build inventory because they will need safe heat stock.

And of course, our distributors will have to get inventory back to the normal levels, which is in the five to seven weeks, but that won’t happen for a while..

That’s very helpful. I guess one final question for me, and you just alluded to it a little bit by saying that the handset market, you have better visibility last quarter, you also highlighted that where you know the share that Huawei is losing and you know the games that everybody else is trying to take on that.

And the latter is bigger than the former.

Any sort of update on how that has progressed? It obviously didn’t seem to hurt you at all in the first quarter, but any update on that dynamic for us?.

Absolutely. You know that we have a very good share in the Chinese OEMs and all of them have benefited from the Huawei situation, more so than non-Chinese OEMs and since we already have a very good share, we indirectly benefited from it. We not only were growing share within their – within their demand.

They also got this additional share from Huawei going away. And so we got the benefit of that. So, I would say that as far as we know, to the best we can cap it, there is not much inventory.

There’s almost no inventory at the power supply guys, meaning the power supply guys who build that after for the Chinese OEMs what we don’t know, of course, is that whether the OEMs have inventory of chargers in anticipation of building more phones and selling more phones to get more share from Huawei.

But overall, I am more comfortable that we are shipping to demand in that market than more fragmented markets because we have no way of at knowing how many appliances are built, how many IoT devices have built, how many HBA devices are built, how many power tools are built. Those are much harder to manage.

They’re also smaller customers, so they don’t have a bandwidth to manage. But we do – what we do is we push back if they’re booking excessively compared to the run rate. We push back and see whether they really react. And they say, yes, we won this new design, we need more parts and we provide them with the parts. But it’s a non exact gain.

It’s – but I think we are doing a pretty good job, by the way..

Thank you for the details, and congrats again, Balu..

Okay. Thanks, Ross..

Thank you, sir. [Operator Instructions] We do have another question from the line of David Williams from Loop Capital. Your line is open..

Thanks and I appreciate you let me ask the question. But the first thing is, congratulations, obviously, on the very strong quarter. But Balu, I think you’ve been right since you’ve been just talking about the market backdrop and what you’ve seen in the inventory build. So clearly, you have a better REIT, I think, on the market than a lot.

But congratulations on the REIT and the steady hand managing the business through this. If I could, maybe a little bit around automotive.

Obviously, you’re not generating revenue there yet, but anything in terms of design activity that you’ve seen? Or maybe what if you could size up that opportunity as we look out over several years, but longer term, what do you think that could be in terms of the size of your business?.

Excellent question. We are making very good progress in getting into a lot of these automotive customers. We have an automotive version of InnoSwitch which is a fantastic fit. Almost every customer who visited wants to use the product. So our expectation is that there will be a lot of design activity going on this year and next year.

But we probably won’t see significant revenue until maybe a couple of years from now because that’s how long it takes to get designed to automotive. Now InnoSwitch is just a bold opener. We have other products, especially the driver products that go into the inverter that drives the motor.

And those products are very good fit as the voltages on the batteries go up. Right now, most of the costs are 400 volts, but there is a strong trend where these cars will move up to 800 volts. And the bigger vehicles, like trucks are already at ETOs.

And at that voltage, we really have an advantage because we have – our drivers have a very robust isolation scheme. That this is using the Fluxlink that we use in the industry, it’s the same isolation.

That provides a significant advantage in that market, plus we have so much expertise in driving IGBT modules and silicon carbide modules that our drivers are far superior in terms of their ability to get the most efficiency out of these modules and to provide the highest level of protection in terms of under abnormal conditions.

So we are very optimistic. It’s just that because we are new to this market, it takes a long time to get there. But all indications are that we will get there. We will have a tiny little bit of revenue this year.

It will grow some next year and the following year, but it really will take two or three years before we go into applications where it is related to the safety of the car, like the motor drive is harder to get into simply because it takes two to three years to go through all the qualifications..

Sure. Makes good sense. But it does seem like you’ve got a large contingency, maybe a product design in that you’re working around. And so once that does ramp, it could be very meaningful longer term.

Is that a fair way to think about it?.

Absolutely, absolutely. We are fully committed to this market. We are working with a number of customers, well-known customers, and we are very optimistic. It’s just a question of time..

Great. Great. And then secondly for me, maybe around the GaN capacity. You’ve obviously had some very good reception there.

And can you talk maybe a little bit just about from a capacity standpoint, what you have in terms of GaN? And maybe there that you’re seeing incremental in terms of maybe winning additional these owns a way to size that up, what the GaN aspect does for your business?.

Sure. We mentioned that our GaN revenue is going to grow at least by three times compared to last year. And every day passes by, we get – feel better about our GaN. The good news is we have plenty of capacity for GaN. And we are also investing more because we see a dramatic growth in GaN over time. And so we don’t expect any restrictions on GaN capacity.

In fact, when somebody brought up the question about how much capacity we have, it really depends on the mix. Obviously, all silicon capacities tied around the world, we are in a much better position because of our proprietary technology and the fact that we are working with partners with the 10-year contracts where they really support us very well.

But when it comes to GaN, that’s completely separate capacity, and we have plenty of it right now, and we will add more to it I don’t see that as a restriction for the – even in the most optimistic case, we can come up with. And that’s also true for high-power. High-power is a totally different capacity, and we have plenty of capacity in high power.

So if those do grow, that’s independent of the capacity that we have on the silicon side..

Okay. Great. And one more if I can, maybe for you, Sandeep.

On the margin, as we kind of think about the mix of both products and maybe even you’re from – in the communications side, thinking about the mix of customers, how do you think that the margin can trend as you move, I guess, from that business, thinking about the third-party or aftermarket chargers and then maybe some of the Chinese OEMs, do you think that margin holds fairly steady? Or could you see some uplift there?.

Well, definitely, in the aftermarket, you will see the margin improvement because it’s higher power level, multiport. And as I had mentioned, the GaN products have much higher ASP generating more, much higher gross margin dollar. But when the volumes are lower, you get even the pricing benefits there.

I think for the year, the gross margin will move in the right direction. And for a year, as we had said, we should still meet our original guidance around the 50% mark for the year.

We do expect the mix in the second half to be a little more favorable than it is for the first half or – because we’ve had a lot of benefit in the first half from the Huawei’s transition. And we do expect that the mix will slightly go favorable in the second half..

Thanks so much. Appreciated..

Thank you, sir. We do have another question from the line of Gus from Northland Capital. Your line is open..

Yes. Thanks for taking the question. Well done, guys..

Thanks Gus..

Quick question – on the semiconductor – I’m sorry, on the cellphone side, how much of your growth is units versus ASP?.

Very good question. We have grown both. But the revenue share is significantly higher than the unit share, simply because our ASPs are much higher, especially when you go to the real high end of the market, we talked about a 65-watt charger for a cellphone, which is a lot of power for the cellphone. They call it the super charger.

You’re talking about significantly higher ASPs than we used to get on the low end of the business. We are talking about five to 10 times more ASP for a simple reason that the power level is very high, one. Secondly, it’s GaN because they’re looking for the smallest adapter.

And to do that, you need very high efficiency, which means you end up having to pay more, the customer ends up having to pay more. But on top of that, we have multiple products in that one charger. It’s a single port charger, but we have three chips in it. One is our pro using GaN as a switch.

The second one is the mini cap, which also uses GaN as a switch, but we also sell CaP 0 [ph], which is another product we introduced some time ago. So, we have a lot more footprint, a lot more dollar content as the whole market moves toward the high end. Right now, the high end is a relatively small business.

You saw – we talked about a notebook adapter using that solution, the same solution being used on the high end of the cellphone. And so it’s actually quite a reasonable volume, but it – I think we have a lot of room for us to grow the content, and therefore, our SAM in the cellphone and notebook market..

Okay. Got it.

And Sandeep, how much in terms of dollars, how much inventory do you want on the balance sheet?.

Yes. Ideally, our model is 120 days. And quite frankly, in the environment, I wouldn’t mind being even higher than that. But I think it’s going to be a bit of a challenge with the demand where it is right now until things normalize. Obviously, the channel inventory, as Balu indicated earlier, we do expect that to pop up a bit in the coming quarters.

I mean, I won’t be surprised even in Q2, it popping back up because two weeks is not sustainable. But internally, I would at least like 120 days, even though in the short-term, I wouldn’t mind being even a little higher..

Okay. And assuming the current revenue run rate..

Yes. And we’re gaining a lot of share. I think what we have tried to tell you is that at some point, things will normalize. And as we talked about having that 16% growth rate, we do see upside sooner and the normalization impact we will see sooner.

So we’ve always started to guide even – I think we will continue to grow our business over the next several years, irrespective of what’s happening in this marketplace right now. Now I know some quarters of the gyrations of demand.

But even as things normalize, in the long term, we believe in our model, because of the share gains that we are seeing across the different end markets. Yes. One thing I want to clarify is that we will outperform, I believe, the industry because of the share gains. So I can’t predict when the normalization of demand is going to happen.

But because of the share gains, we will outperform our peers, we believe..

Let me try to get at the sort of the run rate.

When I think about your older products, they’re pretty steady runners, top switch, tiny and some of the older InnoSwitch products what is the unit volume done over the last couple of quarters relative to what the run rate was?.

It has gone up significantly. I mean, I can’t even believe it. These are legacy products that are – some of them are 25, 30 years old. But the unit volume and the revenue has been growing. And to the point that – believe it or not, we are adding capacity for those old processes and also for the old packages.

These are really all pet packages and escalates. And we still have a capacity because of the demand increasing because these are used in appliances and industrial markets, and those are doing very well..

So can you put a number on it for me? How much is TopSwitch increase from run rate from, I’d say, 2019 to now?.

I’d like to rely on Sandeep here. He is looking at the tables. But I can tell you that it’s still a significant part of our revenue is something like – I think the top switch is in the high-teens percentage of revenue.

And the Chinese switch is in the same high-teens percentage of revenue, and the link with is about low teens of our total revenue, and the rest of it is InnoSwitch-related products..

The InnoSwitch-related products roughly 50% of our revenue..

Right. But what I’m curious about is what has the unit trajectory been? Is it up on the unit....

I don’t have that number..

Yes. We are looking for it. We don’t have it handy. So we can….

We’ll follow up. Yes. That would be super helpful. I’ll let it go. Thanks so much guys..
