Power Integrations DVD/Set-Top Box Reference Design Enables 1-Watt Standby

November 12, 2003
No Heatsink Required in New, Low Cost Power Supply Design Built With Company's New 30 Watt Power Conversion IC

SAN JOSE, Calif. - November 12, 2003 - Power Integrations (NASDAQ: POWI), whose energy efficient EcoSmart® ICs enable consumer electronics manufacturers to meet tightening energy efficiency guidelines for standby and no-load operating conditions, announced today the availability of a new Design Accelerator Kit (DAK-32) for applications such as DVD players/recorders and set-top boxes. The DAK-32 features a cost effective, energy efficient 20 W power supply reference design that easily meets a one-watt standby input power consumption and delivers enough peak power to start motors and spin up drives found in DVD players and recorders.

"This is one more step in Power Integrations' ongoing strategy to use our EcoSmart energy efficient technology and our technical design support capability to enable extremely low no-load and standby power consumption," said Dan Selleck, Vice President of Marketing for Power Integrations. "As a result, manufacturers can meet all current and proposed worldwide energy efficiency guidelines for consumer electronic products."

The DAK-32 is the latest addition to a growing suite of application-oriented power supply design tools from the company. It contains a tested 20 W (25 W peak) universal input AC-DC power supply, PI Expert™ design software, TOPSwitch®-GX power conversion IC samples, and extensive design collateral. In standby mode, the multiple output supply draws less than one watt of input power at 230 VAC while supplying 0.5 W to its load.

The reference design uses a new member of the company's TOPSwitch-GX IC family, the TOP245P, in a 7 pin DIP package capable of delivering up to 30 W of continuous power without requiring a heatsink. By eliminating the heatsink, power supply designers can benefit from a lower system cost and greater reliability. Other high performance features of the TOP245P include a high-voltage power MOSFET with PWM control, fault protection and other control circuitry integrated onto a single CMOS chip, built-in soft-start, 132 kHz switching frequency (automatically reduced at light load), frequency jittering for low EMI, wide maximum duty cycle, and hysteretic thermal shutdown.

The DAK 32 design accelerator kit is priced at $45.95 each and is available for ordering at Power Integrations' Web site, www.powerint.com.

Power Integrations is a leading supplier of high-voltage analog integrated circuits for use in power conversion. For more information, contact the company at 5245 Hellyer Avenue, San Jose, California 95138, PH: (408) 414-9200 or visit the company's web site at www.powerint.com.

Safe Harbor Statement

This press release contains forward-looking statements, which reflect management's current forecast of certain aspects of the Company's future business. These forward-looking statements are based on current information, which we have assessed, but which by its nature, is subject to rapid and even abrupt changes. Forward looking statements are denoted by the use of such words and phrases as "will," "expects," "believe," and similar words and phrases that look toward future events or performance. The Company's actual results could differ materially from those projected or implied by our forward looking statements due to risks and uncertainties associated with the Company's business. These include, but are not limited to, changes and shifts in customer demand away from products which integrate the Company's ICs to products which do not; the lengthy sales cycle for the Company's products which often results in the Company incurring substantial expenses before the Company generates significant revenues, if any, from the sale of a new product or even before a customer, if any, decides to use the new product in any of its products; and the associated risk that the customer's product in which the Company's new product is used will not be commercially successful due to a variety of factors including cost relative to competitive products at the time the customer's product enters the market. Other factors include, but are not limited to, our ability to maintain and establish strategic relationships; the risks inherent in the development and delivery of complex technologies; our ability to attract, retain and motivate qualified personnel; the emergence of new markets for our products and services, and our ability to compete in those markets based on timeliness, cost and market demand; and our limited financial resources. We more fully discuss these and other risk factors in the Company's most recent reports on Form 10-K and Form 10-Q filed with the Securities and Exchange Commission.
