And now, I'll turn the call over to Balu. .

Thanks, Joe, and good afternoon. First quarter revenues were $83.1 million below our forecasted range but, nonetheless, 8% higher than a year ago. Non-GAAP earnings per share grew nearly 20% year-over-year, as our gross margin increased to its highest level in nearly 8 years..

We generated solid cash flow and further strengthened our balance sheet, prompting our Board of Directors to raise our dividend just 2 quarters after the most recent increase.

We also made good progress during the quarter on our key growth initiatives and we expect healthy sequential revenue growth in Q2, with accelerated growth likely in the second half of the year as we roll out an exciting new technology that has received an enthusiastic response from customers and has already won a number of high-volume designs.

I will talk more about that in a moment. But I, first, want to address the first quarter revenue shortfall, which came primarily from the computing and communications end market..

Sales into the computer market declined nearly 20%, sequentially, due to a sharp reduction in sell-through for desktop power supply applications. This appears to have been nothing more than a ripple in the supply chain, similar to what occurred in the first quarter of last year when our computing revenues declined by an identical percentage.

Importantly, even after the sequential decline, our revenues from the PC market in the first quarter of 2014 were up more than 10% year-over-year, reflecting significant market share gains in both main and standby power supply over the past year. .

That bodes well for the rest of 2014 if we see a repeat of last year when the soft first quarter was followed by 3 consecutive quarters of strong sequential growth in PC applications. It was also a challenging quarter in the communications end market with the revenues down about 20% sequentially.

This market tends to be unpredictable, given a high level of competitive churn and the preponderance of high volume applications, but multiple factors converged to make this an unusually volatile quarter..

One of our largest customers, a manufacturer of small-scale networking equipment, pushed out a substantial amount of demand that had been in our backlog at the time we gave the revenue forecast..

We also saw lower revenues from cellphone charges due to a slowdown in demand at our largest end customer, as well as churn at the low end of the market, where market share tends to shift frequently.

While our first quarter revenue are disappointing, we believe they are largely the result of short-term market fluctuations with virtually no implications for our long-term growth trajectory.

We are as bullish as ever about the opportunities ahead of us in areas like LED lighting, rapid charging for the mobility market, and our expansion into higher power applications, which has already added $1 billion to our addressable market, with more to come as we expand our mid- and high-powered product portfolios..

We are also heavily focused on the rollout of a revolutionary new technology that we plan to launch formally later this year, but have already introduced to key customers for high-volume applications.

Incorporating primary and secondary circuits as the last safety isolated feedback, all in a single device, we believe this new technology offers the most radical simplification of low-power AC-DC power supplies since the introduction of our groundbreaking TOPSwitch family 2 decades ago..

The first product incorporating this new technology has already been designed in by several smartphone vendors for rapid-charging applications, and we expect initial shipments to begin in Q2 with volumes ramping through the second half of the year.

The new technology also dramatically improves, active mode efficiency and arrives just in time for a new round of energy efficiency standards in the U.S. and Europe..

In February, the U.S. Department of Energy announced substantial revisions to its mandatory standards for external power supply, making them easily the most stringent power supply efficiency standards anywhere in the world..

Set to take effect early 2016, the new standards include tighter active mode efficiency requirements and much stricter limitations on standby consumption, going from current levels of 500 milliwatts to a challenging 100 milliwatts for most external power supply..

Meanwhile, the European Union voluntary Code of Conduct specifications for external power supply were tightened effective January of this year, with a further tightening set to take effect in 2016.

We expect a wave of redesign activity in external power supply as we approach the effective date of these new standards and we believe our technology will -- our new technology will position us to capture a significant share of this market..

Another key element of our growth strategy is LED lighting, and we expect growth in that market to accelerate this year as prices on LED lamps continue to fall and our -- and as our highly integrated light switch product family continues to get strong traction in the marketplace..

We won a large number of designs in Q1 ranging from streetlights to replacement bulbs, including a high-volume design for a major home furnishing retailer and another for a name brand bulb manufacturer..

We also had a strong quarter in our higher-power market, winning new designs for main power supplies in both TV and PC applications, while our CONCEPT IGBT drivers continue to gain share in attractive end markets like renewable energy, electric transportation and energy exploration..

In March, we announced the first shipments of drivers featuring our latest chipset known as SCALE-2+ plus in products targeting solar inverters, uninterruptible power supply and industrial motors.

This next-generation technology enhances our already industry-leading level of integration, enabling greater reliability, ease of design and smaller board footprint..

We won several high-value designs in the first quarter, including wind inverters for China and India, and a large solar inverter project at a Canadian customer. And we believe we are on track for another year of double-digit growth in high-power..

Before I turn it over to Sandeep, I would like to touch on the latest development in our long-running patent litigation against Fairchild Semiconductor..

Last month, a jury in federal district court in California found that Fairchild and its System General subsidiary, infringed 2 of our patents and awarded damages of $105 million. The infringement was found to be willful, which means the court could enhance the damages up to 3 times the amount awarded by the jury..

In addition to enhanced damages, we are seeking a permanent injunction against the more than 150 infringing Fairchild products implicated in the decision and any other products with infringing circuitry.

These products would be in addition to 100 products already under permanent injunction based on an earlier litigation and more than 80 other products for which we are already seeking injunction based on a case decided in 2012..

This marks the fourth time Fairchild and SG have been found to infringe our patents, and we hope that this latest decision will cause Fairchild to finally re-exam its business practices and begin respecting our intellectual property rights..

With that, I'll turn it over to Sandeep for a review of the financials. .

Thank you, and good afternoon. I will review the Q1 numbers and the outlook, and then we will open it up for Q&A..

In my prepared remarks, I will focus primarily on the non-GAAP numbers, which are reconciled to the corresponding GAAP numbers in the tables accompanying our press release..

First quarter revenues were $83.1 million, up 8% from a year ago. We had double-digit year-over-year growth in 3 of our 4 end market categories, with only the communication end markets showing a decline from the prior year..

Sequentially, revenues were down 8% with consumer roughly flat, industrial down mid-single digits and both computer and communications down roughly 20%..

The revenue mix for the first quarter was 37% consumer, 35% industrial, 18% communication and 10% computer. Our non-GAAP gross margin increased nearly 2 points from the prior quarter to 56.4%, its highest level since 2006. The increase was primarily due to end market mix as the softer than expected demand came in lower-margin end markets..

A small incremental benefit from last year's depreciation in the dollar versus the Japanese yen also contributed to the gross margin improvement..

Non-GAAP operating expenses for the first quarter were $28.4 million. That's below our forecast due, in part, to litigation expenses and also a number of expense-saving measures we implemented in the later part of the quarter in response to the weaker revenue.

Our non-GAAP tax rate for the first quarter was 6.3% up from the last year, reflecting the expiration of the federal R&D tax credit, but in line with our expectations..

Non-GAAP earnings for the quarter were $0.56 per diluted share, up 19% from a year ago, when we earned $0.47. We generated $16.2 million of cash flow from operations in the quarter, while capital expenditures totaled $4.5 million. Cash and investments on the balance sheet totaled $217.7 million at quarter end, up $15.5 million during the quarter..

As Balu indicated, our Board of Directors has declared a 20% increase in our quarterly dividend effective in the third quarter of this year when the dividend will rise to $0.12 per quarter. We also have approximately $30 million remaining on our buyback authorization.

Internal inventories increased by $5.7 million, during the quarter, partly as a result of lower than expected sales, but also in anticipation of the growth ahead of us. We had 118 days of inventory on hand at quarter end, which is within our targeted range of 110 days plus or minus 15. .

As for the outlook, we expect second quarter revenues to be in the range of $89 million plus or minus $3 million, which would be up 7% sequentially at the midpoint..

Non-GAAP gross margin should be roughly 54.5%, reflecting a combination of less favorable end market mix, lower production volumes and the initial ramp of new products. I expect non-GAAP operating expenses to be between $29 million and $29.5 million in the second quarter.

That's an increase from Q1 due, in part, to the timing of the annual salary increases which are effective April 1. I then expect OpEx to remain at a similar quarterly run rate through the second half of the year..

Lastly, I expect the non-GAAP tax rate for Q2 in the balance of the year to be approximately 7%..

With that, I'll turn it back over to Joe. .

Thanks, Sandeep. We will open it up for the Q&A session now.

[Operator Instructions] Operator, would you please now give the instructions for the Q&A session?.

[Operator Instructions] Your first question comes from Andrew Huang with Sterne. .

So the first question is with respect to communications. So I understand that it was down sequentially for the March quarter.

But I was wondering if you could give us a little bit of color or maybe conviction that it's not share loss, and when I look at your margin guidance for the June quarter it would suggest that there's probably going to be a rebound there? But any more color would be helpful. .

one is cellphones, the other one is networking area, where we had a shortfall. In the networking area, one of our largest customers and who has been a very, very successful customer in this area. They make wireless routers. We've had a very high share of this customer and they have been growing very rapidly.

And it looks like their demand slowed down after a very significant increase over the last couple of years. They are almost 5% -- not quite 5%, but slightly less than 5% customer. And what happened was in February, they pushed out a significant portion of their orders.

So it was actually on the books when we gave the revenue forecast, but we found out later that they wanted their orders pushed out. It's not clear when it will come back. So we are conservatively assuming that it's not going to come back in Q2 very significantly. So that's one portion of the shortfall. In the cell phone area, there are several reasons.

One is that one of our largest end customers, they have multiple suppliers. And two of their suppliers reduced their demand unexpectedly. We were expecting them to order in the normal pattern, but we found out that the demand has declined, so they reduced their orders. So that's one aspect of it.

The other one is that we -- in the low end of that market, which is primarily feature phones, there was a shift in the share of one of our customers. There are usually multiple customers supplying to an end OEM. And it's not uncommon for the share to shift back and forth.

And unfortunately, one of our customers lost a significant portion of their share to one of their competitors, who does not use our solution. And then there was another case where we chose to walk away from a low-end phone opportunity because the pricing was irrational, and we do that all the time, as I've explained it in the past.

So it was kind of perfect storm. Everything happened altogether, and that's what affected the communications market by 20%, sequentially. .

Got it, okay. And then maybe -- I think you mentioned briefly about this revolutionary new technology for the second half of the year.

So I think everyone would appreciate a little more color on what that technology is and in what applications it could be used for?.

The technology is very fundamental, meaning it can be used with any application in the low-power, maybe even into the mid-power. And what that allows us to do, for the first time, we are able to combine not only the primary side of the power supply, which is what we have been always integrating in the past.

You take TOPSwitch or TinySwitch or LinkSwitch, it's all on the high-voltage side. But this technology allows us to combine the primary side or the high-voltage side electronics with the secondary side or the low-voltage side on the same device.

And to do that, we have to provide safety isolation and also communication because the feedback signals have to flow from the secondary to primary through a safety isolation. And we have a very clever way of doing that in a single device.

And we have gotten approvals from all of the safety agencies around the world, and so we are ready to go into production with this device. Now the first product using this technology is targeted towards adapters, specifically for mobile devices. Whether it's cell phones or tablets or even laptops in the future.

So that product, for the first time in the world, we are able to combine both sides, which also gives us a lot more flexibility in doing some clever things from the secondary side, which we never played in the past.

For example, we do work on a circuit rectification on the secondary side, which increases the active mode efficiency significantly and allows us to easily meet the DOE requirements that will take effect in 2016.

And of course, on the standby side, we have always had extremely low standby consumption and this will take it even further and allow us to meet standby consumption in -- to less than 10 milliwatts. So hopefully, that gives you sufficient color. .

Okay.

If it's okay, can give us some color on ASP or margin for that new product?.

I can't talk about ASP, but let me give you some rough idea. So if you take just the primary side, let's say, the cost is -- I mean, the price is 1x, the fact that in implementing secondary side and the isolation will give us at least 2x kind of a ASP.

And of course, if we implement more complicated secondary side functions, that could increase incrementally from there. .

Your next question comes from Tore Svanberg from Stifel. .

This is Evan calling in for Tore.

Could you talk a little bit about how high-power performed this quarter? It sounds like a bulk of your revenue relied on this sector this time?.

The high-power revenue was slightly down this quarter, but that's just a quarter-to-quarter fluctuation. The high-power revenue, to the extent we can tell, does not have any seasonality.

It's not like the general industrial market, where it's the strongest in Q1 because it goes into a lot of infrastructure projects, which are determined more by timings of major infrastructure improvements in various countries. But having said that, we are very bullish on the high-power for the year. We expect it to grow double-digits this year.

So there is really no concern at all about it being slightly lower in Q1. .

Okay, great.

Also, just looking at -- going back to your guidance, can you give us some sense about where you are in your backlog in supporting your guidance? And also, whether there could be some upside to your guidance, where that upside might come from if things turn out to be more favorable than you think right now?.

So in terms of backlog, as you realize, we recognize most of our revenues, 90% of our revenue on sell-through basis. And so our backlog is not very meaningful indicator of the actual revenue. Having said that, we obviously take that into account for our forecast. So it is consistent with our forecast.

We generally don't like to give the backlog to-date because it can be misleading in many times. And I think your other question was related to whether there are any upsides. Of course, there is always upside, but we have to go by what we know today.

If -- in general, Q2 is very broad-based increase for us, we see improvements in LED, PC standby, because we had such a sharp downturn in Q1 in PCs. We expect that to come back. So it depends on how much or how far it comes back. And we also see growth in mid-power and high-power in Q2. .

And Evan, as Balu mentioned in his prepared remarks, we see accelerated growth in the second half with all these new introduction products, including the revolutionary product. .

Your next question comes from Steve Smigie from Raymond James. .

This is Vince Celentano speaking for Steve Smigie. I was wondering if you can go specifically, speak about the CT-Concept business as far any kind of share gain opportunity.

If you think within the next 12 months, roughly a 2% increase seems realistic?.

I'm trying to find some design wins. So we had a significant design wins in the high-power area. Both with the new technology that was recently introduced, which is the SCALE+ -- the SCALE-2+ and also with the existing projects.

So we won a design for wind power, I think I mentioned in my report -- I mean, written -- sorry, prepared script, in China and India. And also, we are seeing a lot of opportunities there. We have won designs for oil exploration. Actually, it's frac-ing, I should say.

So the other thing that's happening around the world is that solar is becoming more and more attractive. It has hit a great parity in many parts of the world. So we are seeing solar coming back after a long time of softness. So we see a lot of opportunities and we expect, as I said, double-digit growth this year. .

Okay, great. And moving on to white goods, I was hoping, if you can give kind of a forecast on that and if you think, roughly 2 times GDP seems about right over the next 12 months? And I guess any kind of color on that would be great. .

Okay, that's an area -- another area we are doing extremely well. In fact, even in Q1 the appliance did really well. And we have a number of design wins in appliance and we expect appliance to continue to grow. It's a very sticky market, so we are very excited about that part of the market. .

And we are also getting multi-chip opportunities in the appliance area. So that -- and so we are seeing much more growth coming through multiple chip sales in the unit. .

Your next question comes from Ross Seymore from Deutsche Bank. .

This is actually Matt Diamond on Ross Seymore's behalf. And I wanted to ask you about the guidance with respect to your end markets. If you could just give us an idea of what would be expected to be up most and least? Just sort of a stratification of your 4 different segments there. .

Sure. Let's start with industrial. In the industrial, we expect LED to be up. We expect the high-power to be up. And in the consumer, we expect the appliances, which is slightly more than 2/3 of the market, to be up. And in computers, we expect the -- both the standby and PC main markets to be up in Q2.

The only area we think is not going to be significantly up is communications. We are basically assuming that it's not going to come back strongly, except for the new products we'll start shipping in Q2.

And that will be in the order of maybe $500,000 to $1 million worth of revenue in Q2, but it will be significantly higher in Q3, as these rapid-charging programs go into production. And then it will continue to increase in revenue through the fourth quarter of this year. .

Okay. And the gross margin, it looks like it's down roughly 2 points sequentially, and it was mentioned that there's a function of less favorable mix, lower volumes and these new product ramps.

If you could just sort of specify what exactly would drive this gross margin down the most? And what -- how we should expect it to potentially ramp up in the second half of the year?.

So I think in the second quarter, the impact of the gross margin for the 3 items you asked about is about 1/3 each. But in the third and fourth quarter, we expect the margins to go down further as we are ramping new products, as well as ramping the revolutionary product in the second half.

Overall, if you are looking for an overall, if you remember in the last quarter, we had said that the gross margin for the year would be about 50 -- based on a non-GAAP basis, would be about 50 basis slightly below 2013. Which is about 53.8%.

But considering, the favorable gross margin in the first half -- first quarter that you've seen, we expect the overall gross margin should be slightly higher. But the gross margin in the second half, even though it's going down, will stay well within our targeted range. .

[Operator Instructions] Your next question comes from Vernon Essi from Needham & Company. .

I was wondering, Balu, if you could give me more details on the rapid-charge front or quick charge front, and what you're seeing out there in the marketplace?.

Absolutely. In terms of rapid charging, almost every OEM we have spoken to wants to go into rapid charging. So that's not an issue at all. Everybody will do rapid charging.

In terms of the quick charge protocol, that's a Qualcomm protocol, we had seen a significant number of customers who have decided to use Quick Charge, at least on some of their models. I think that the last count, it was about 9 of the OEMs, who have decided to use Quick Charge.

The real question is how broadly they will use Quick Charge going forward? But we are very enthused by the acceptance of Quick Charge. There are still a few OEMs who have not made a decision yet. They are evaluating Quick Charge, along with a couple of other protocols. And we are closely monitoring the situation.

We are engaged with all of those other customers. As far as we are concerned, whether it's Quick Charge protocol or some other protocol or no protocol at all, is somewhat octagonal [ph] to what we want to do, which is sell our power-conversion chips. For example, this new technology we talked about will go into any kind of rapid-charging application.

And if it is Quick Charge, we will also sell the protocol chip, which is the CHY100 chip that we announced last year. If not, we will sell the power-conversion chip, which is the new technology, which happens to be the significant portion of the dollar content in the charger. .

Okay, so -- and I just want to be clear, too. You're probably -- I'm noticing you're not getting into any details or milestones versus the last couple of calls in terms of discussing any new design wins. I mean, is that something you're going to discontinue to do or has there been any newer design win activity to speak of on the... .

No, I can certainly comment on that. We have roughly about 6 companies, 6 OEMs who are going to use our product. About half of them -- or 3 of them are using Quick Charge, the other 3 are using rapid charge without the Quick Charge protocol.

And as I mentioned earlier, 9 of them have already committed but they have not gone into a preproduction or they haven't place orders, so we don't consider them as design win at this point. In addition to that, there are a number of other customers in evaluation. So expect to get more design wins in Q2. .

Okay. And then just 2 sort of, I guess, housekeeping.

First related to the charger side, what's your sort of rule of thumb in terms of how much of your revenue and obviously, it's in the communication segment, but how much of that is typically charger on a full run basis? And should we be thinking about that to change, given the fact that you've had this sort of setback on the networking side?.

So I think what you are looking for is how much is cell phone as a portion of the total communication. It's still running at about half. And I think with the revolutionary new product coming out and that depending on the power levels and where it gets applied, I think over a period of time, you should see that, as a portion, go up. .

Okay. And then finally, on LED, you had some prepared comments and even your press release discussing it. How did that business do in terms of overall revenue? Any hints you can give us as to how that's growing? And any potential targets you might have for the revenue for 2014 would be appreciated. .

Sure. Our revenue in LED is in the high single-digits. So it is -- there are 2 major applications within industrial. And the #1 is high-power, the #2 is LED. High-power, as you know, is slightly over 10% and LED is slightly below that. And we expect a number of new design wins we have going into production in Q2.

So we expect to grow LED revenue through the rest of the year. .

There are no further questions at this time. I'll turn the call back over to Mr. Shiffler. .

Okay. Thank you, and thanks, everyone for listening. There will be a replay of this call available on our site, which is investors.powerint.com. Thanks again for listening, and good afternoon. .

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