Thanks, Joe, and good afternoon. This was a record revenue quarter for Power Integrations with sales of $97.2 million, up 14% from a year ago. Non-GAAP earnings were $0.60 per share, up more than 25% year-over-year, and we generated $23.6 million in cash flow from operations in the quarter.

For the first half of the year, revenues increased 9% comparing favorably to the broader analog semiconductor industry, which most likely experienced a slight contraction in the first half of the year.

The primary driver of our growth in the first half has been our success in the smartphone charger market, which is undergoing dramatic technological changes driven by a pair of inherently conflicting trends in the mobile device market.

On one hand, OEMs are incorporating larger batteries in their phones in order to improve battery life while supporting bigger displays and other power-hungry features. On the other hand, device makers are also pushing to reduce charge time in order to reduce downtime for end users.

These seemingly incompatible objectives can be met only with a drastic increase in the power level of smartphone chargers and that is exactly what we are seeing in the marketplace. Just two years ago, virtually all mobile phone chargers were delivering 5-watts or less.

This year, hundreds of millions of smartphones will ship with higher power chargers ranging from 7.5 watts to as high as 20 watts. Nearly, all top tier OEMs are now participating in this trend. And all of those are using our products in high volume.

While increasing power level of a cell phone charger may sound routine, the fact is that rapid charging introduces difficult trade-offs for power supply designers.

In order to deliver two times, three times or even four times as much power out of a charger while maintaining a small form factor, designs must be extremely energy-efficient and component count kept as low as possible.

Integration is a key to solving these challenges, and we believe our InnoSwitch products are the most highly integrated power conversion ICs on the market. While earlier products were confined to the primary are high voltage size of a power supply, InnoSwitch travels the barrier between primary and secondary sides of the circuit.

This allows us to integrate components from both sides of the safety barrier, enabling dramatic improvement in performance while reducing component count, complexity and size. These characteristics make InnoSwitch extremely well suited for rapid charging applications and that's clearly reflected in our recent results.

Revenues from our communications category, which includes mobile phone chargers, are up more than 30% in the first half of 2016. This growth reflects not only our increasing share of the charger market, but also our rising dollar content which spans from the combination of rising power levels and the higher level of integration offered by InnoSwitch.

While rapid charging has already had a significant impact on our results, we expected it to be a growth driver for years to come. This is for a number of reasons. First, penetration of rapid charging is still in the early stages, and even existing designs will continue to migrate to higher power levels over time.

Second, new technologies such as the USB PD, direct charging and Type-C connectors are just beginning to emerge. And all of these technologies will drive the need for more innovative power conversion ICs. Third, rapid charging has huge potential beyond mobile phone markets, particularly in tablets and notebooks.

And finally, as successful as InnoSwitch has already been, we believe the next-generation devices due out later this year will be even more attractive. Perhaps more importantly, rapid charging represents just a fraction of the opportunity for InnoSwitch in the AC to DC power supply market.

InnoSwitch has already won designs in more than a dozen non-cell phone applications in all four of our end market categories, and we have designs in progress at nearly 400 customers.

We expect that further acceleration of design activity, once we introduce the next edition InnoSwitch, which not only offers a higher level of performance but also addresses significantly higher power levels.

While we expect the InnoSwitch product cycle to be a multiyear growth driver, our growth opportunities extend well beyond the AC to DC power supply market. So far this year, we have introduced four new members of our LYTSwitch product line as we continue to refine our offerings for increasingly fragmented LED lighting market.

Lighting revenues are on track to grow this year, and we expect even faster growth next year as our latest LYTSwitch products begin to ramp. In May, we introduced SCALE-iDriver, a new line of IGBT drivers targeting applications between 10 kilowatts and 100 kilowatts.

SCALE-iDriver is the first product synergy from our 2012 acquisition of Concept, combining our SCALE IGBT driver technology with the FluxLink technology used in our InnoSwitch devices. The result is an IC that brings an unprecedented level of integration to a market that has historically relied solely on discrete design.

Applications include industrial motor drives, commercial and residential solar, medical equipment, electric vehicles and more. We estimate this market to be $0.50 billion in size bringing our total market opportunity for IGBT drivers to roughly $1 billion.

All told, our served available market now exceeds $3 billion and we expect it to grow further in the years ahead. This expansion will be driven in part by product introductions that enable us to address power conversion applications where we don't currently have a presence.

But it also comes from growth in a number of verticals in which power silicon content is rising.

For example, electronic content in consumer appliances has been steadily expanding, thanks to stricter energy efficiency requirements and the migration from mechanical to electronic control, a trend that should continue as IoT functionality comes to market.

Meanwhile, older lighting technologies are giving way to LEDs, which require AC to DC drivers and mechanical utility meters are being replaced by electronic meters that need efficient, reliable power supplies.

Other trends include electrification of transportation and the increasing use of rechargeable batteries in products such as power tools, lawn equipment and bicycles. In summary, our first half results were strong and we are gaining market share across a broad range of power conversion applications.

And we believe we are poised for continued above-market growth, thanks to a robust product cycle and an expanding addressable market. The high voltage power conversion space continues to evolve in ways that demand integration and energy efficiency. And we are responding with some of our most innovative products ever.

And with that, I will turn it over to Sandeep for a review of the financials..

Thanks Balu, and good afternoon. I will quickly touch on a few financial highlights and then we will open it up for questions. As usual, my remarks will focus mainly on the non-GAAP numbers, which are reconciled to the corresponding GAAP figures in the tables accompanying our press release.

Q2 revenues were $97.2 million, an increase of 14% sequentially with growth across all four end markets. Communications revenue increased more than 35% sequentially, driven mainly by the continuing graph of rapid charging design for the smartphone market.

Industrial revenue increased more than 10% sequentially on broad-based strength including LED lighting, high power and metering applications.

Sales into the computing market increased mid single-digit sequentially, while consumer revenues also grew mid single-digit on strength in appliances, most notably air-conditioning applications, which typically reach a seasonal peak in the June quarter.

The relative strength in communication revenues resulted in a meaningful shift in end market mix with communications increasing 4 percentage points sequentially to 27% and consumer falling 4 points to 35%. Industrial and computer held constant at 32% and 6%, respectively.

This change in mix was the primary factor in the sequential decrease of 130 basis points in our non-GAAP gross margin. Looking ahead, we expect gross margin to remain fairly steady in the second half as end market mix should be a bit more stable than we have seen over the past couple of quarters.

Non-GAAP operating expenses in the second quarter was $30.7 million that's up sequentially as expected, reflecting annual merit increases and accelerated R&D spending as we work to bring a larger-than-usual number of new products to market.

Nevertheless, non-GAAP OpEx came in slightly below our forecast for the quarter and increased less than 2% from a year ago. Non-GAAP operating margin was 18.7%, up 120 basis points sequentially reflecting the strong revenue growth.

Our non-GAAP tax rate for the second quarter was just over 4%, resulting in non-GAAP net income of $17.7 million or $0.60 per diluted share. That's up from $0.50 in the prior quarter and $0.47 a year ago. We generated $23.6 million in cash flow from operations in the quarter, while capital expenditures totaled $2.8 million.

Cash and investments on the balance sheet increased by about $17 million during the quarter to $202 million. Internal inventories increased slightly in terms of dollars, but fell to 86 days on hand, a decrease of 12 days from the prior quarter reflecting the stronger-than-expected revenue growth.

We do expect to build some inventory in the second half to get back into our target range of about 110 days, plus or minus 15 days. Our outlook for the third quarter is for revenues of $96 million to $102 million, which would be up more than 10% year-over-year at the midpoint.

As mentioned earlier, we expect end-market mix to be fairly stable, which should result in a gross margin similar to the Q2 level. Specifically, we expect non-GAAP gross margin to be in the range of 50% to 50.5% for the September quarter.

Non-GAAP operating expenses should increase slightly to around $31 million, while the non-GAAP tax rate should remain in the range of 4% to 5%. With that, I'll turn it back over to Joe..

Thanks, Sandeep. We'll move on to the Q&A session now.

Kelly, would you please give the instructions for Q&A?.

Sure. [Operator Instruction] The first question comes from the line of Christopher Longiaru of Sidoti Company. Your line is open..

Hey, guys. Nice execution..

Thank you..

Thank you..

My first question has to do with, you talked about the end market expansion. Can you give us just a little clarity into what the timing on some of these products are because obviously the consumer stuff is quicker right, and some of the other stuff takes longer.

So, just to get an idea of how you see infiltration of that going forward?.

It is true, Christopher, that certain markets are faster. So, if you look at what has increased the addressable market this year, is primarily the iDriver, SCALE-iDriver, which adds 500 million to our 2.5 billion addressable markets. So that brings the total to 3 billion.

However, we have additional products that are coming out, including our next edition InnoSwitch that'll add to the addressable market this year, and plus some additional products next year that'll expand the market further. So, I would say, in terms of time to revenue, some of the lower power markets are faster.

They are typically in the six-month to 12-month range that as the high power products tend to be more in the year to year-and-a-half kind of a design cycle, for example, for the iDriver..

Got it. Okay. And the only other question I had was, so that the mix was the factored at pressure gross margin that – was there any Yen effect in terms of, I think, it takes two quarters to three quarters for the strengthening Yen to show up – for the weakening Yen to show up versus – and the same thing for strengthening Yen.

Can you just give us a little idea of, if there's any contribution to that in your gross margin number?.

The Yen hasn't had an impact yet, it'll start having an impact in Q4. And you're correct, it takes about five months to six months. But as you know, the Yen has been moving through this year from the ¥120s down to somewhere in the ¥105, ¥106 level.

So the unfavorable impact will start in Q4 and – if it remains at the current level more so in the next year, however, a lot can change between now and the end of the year. So it's hard to predict the full impact for the next year, but the start of the yen impact is more so in the Q4..

That makes sense. Okay.

And then last thing is just on the rapid charging front, how penetrated would you say the market is and how much of that penetration does POWI own at this point?.

It's a little difficult to calculate that because it's such a dynamic market right now. So the best we can estimate, roughly one-third of the smartphones have started using rapid charging. As far as our share, we think there are really clearly two leading solutions. One of them is ours.

I would say that in terms of dollar value-ship, we are clearly number one..

Okay. All right. I understand. Thank you, guys. I appreciate it..

Thank you..

You're welcome..

Your next question comes from Ross Seymore of Deutsche Bank. Your line is open..

Hi, guys. Congrats on the strong quarter. Just looking at the upside in the quarter, obviously, we know in retrospect where it came from, but just talk a little bit about how the quarter played out and how it differed so much from your original guidance..

Well, clearly, we've done better than we expected in the cellphone or the communications market I should say, particularly, in the rapid charging market with InnoSwitch. We have exposure to all of the Tier 1 customers except one. And the ones in China have done extremely well, and particularly there is one Chinese OEM who has done extremely well.

But I would say that all of our Tier 1 customers have done well in terms of rapid charging products we ship to them. And we got to be careful, because when we ship rapid charging products, it's not only the unit volumes, but it's also the content is so much higher for us.

So, our revenue doesn't necessarily reflect the number of units of smartphones or even rapid charging phones. But as far as we are concerned, it's been a significant growth in that market. The second area where we've done very well, of course, is industrial, where we've grown double-digits sequentially.

And that has been across multiple areas including high power, LED, metering, electric charges for electric vehicles like bicycles, and also charges for power tools and lawnmowers and so on and so forth. It's very, very broad based. So, those are the two main areas..

So, I guess, looking forward, Sandeep, you talked about the mix remaining relatively stable. In this last quarter, I, kind of, flipping the question from the first questioner on its head. Given the strength in the communications side, I'm actually surprised that you're able to stay pretty close to the low end of your margin range.

Are you starting to get any cost benefits from the higher volume of the InnoSwitch products?.

Absolutely. And that's why I think we are able to talk about the margin remaining, even though the Yen is going to start impacting us in Q4, it is the higher volume that we're going. We don't have our own fab. We don't have as much fixed cost, but we do have some fixed cost.

And that is what is actually enabling us and helping us offset the Yen impact that we are starting to see. And that's why we were mentioning that we expect the margin to remain in the level compared to Q2 for the rest of the year, and the mix also to remain the same..

And I guess as my last question. Any sort of color on the channel inventory. I know you guys recognize on sell-through.

So, it's not a revenue issue as of today, but did that get depleted down to a level that you're comfortable that you're not going to have any sort of a digestion after such a big pop in the communications side?.

No. The weeks in the channel are down from – last quarter, was 7.3 weeks, which is, as you know, was mainly because of Chinese New Year. And now it's down to 6.5 weeks. So, typically we run at 5.5 weeks, six weeks. So, you may say it's slightly, but it does not – I won't say, of any significance..

Okay. Great. Congratulations again..

Thank you..

Thanks, Ross..

And your next question comes from the line of Tore Svanberg of Stifel. Your line is open..

Yes. Thank you. Nice quarter. First question, can you talk a little bit more about your relative visibility going into the quarter? I know in Q2, obviously, you had the sell-through phenomenon from Q1.

So, as you head into the September quarter, where do you stand on backlog?.

Our backlog is better than in the past. As you've noticed that our turns have been gradually going down. So, we've built a reasonable backlog in Q2. Our bookings in Q2 was sequentially better than in Q1, consistent with our forecast for Q3. So, I think, we are in a stronger backlog position than we were in Q2 for Q3..

Great. Thanks. And, Balu, as we look at InnoSwitch impacting the rapid charge market and you talked about power levels continue to go higher and higher.

How should we think about that in light of your prices? So, would you have higher content, let's say, in a 7.5-watt charger versus a 20-watt one?.

Absolutely. One of the unique things about our product is, it integrates a switch in it. As you go to higher power levels, your content is higher, and therefore, our ASP would be higher..

Very good.

And then lastly, could you also elaborate a little bit on the latest PEM (24:00) extension that you have? When should we start to think about revenue contribution from the product you just released here back in May?.

I'm sorry, I wasn't sure which – what part?.

iDriver..

iDriver, okay..

Yeah. Correct..

So, the iDriver was introduced in May, this year at CCIM Europe. The interest level is very high. The feedback is extremely positive. We don't expect any revenue this year, but we do expect some revenue next year based on the feedback we've seen so far. As I said, it typically takes year to year-and-a-half for that type of product.

It goes into markets of renewables, UPS, power supplies, motor control and so on. And my expectation is, we should have some revenue in the second half of next year..

Great. Actually one last question for Sandeep. Sandeep, inventory days now down about 15 days, 20 days below your target.

How do you feel about the actual level going into the September quarter? You mentioned you're trying to build some, but are you worried at this point about some constrains or you should be able to catch up?.

So, basically, we are keeping – our lead time is the time except for obviously certain products where because we've had such a demand that we are a little tighter, but we are actually ramping up our production as well as at different places. So, we believe that over the next two quarters, we should get back into our range..

Very good. Great quarter, guys. Thank you..

Thanks, Tore..

And there seems to be no further questions at this time. I turn the call back over to the presenters..

Okay. Well, I know it's a busy day out there for earnings. So, appreciate everyone listening in. There'll be a replay of this call available on our website, which is investors.power.com. Thanks again for listening and good afternoon..

This concludes today's conference call. You may now disconnect..
