Power Supply Software Now Supports Designs Up to 250 Watts

February 1, 2001

San Jose, CA, February 1, 2001 – High-voltage analog integrated circuit specialist, Power Integrations, Inc. (Nasdaq: POWI), announced today the availability of the latest version of PI ExpertÔ , the company's software program which significantly reduces the amount of time to design an optimized switching power supply. As with its predecessor, users simply enter their power supply input requirements, output requirements, and optimization preferences. In less than five mouse-clicks, the program determines the critical components needed for a working switch mode power supply, including the best TOPSwitchÒ power IC, input capacitor, and complete design details for the transformer. The transformer is usually the most difficult and time-consuming portion of the design process.

Version 2.5 of the PC-based design program includes a variety of design enhancements, including support for the company's new TOPSwitch-GX product family, the industry's first monolithic high-voltage power conversion IC capable of delivering up to 250 Watts. Other enhancements include DC input capability and an enhanced calculation engine for improved accuracy. In addition, the new version contains demonstration files presented in Mandarin, Japanese, and Korean languages. A complete library of the company’s data sheets, application notes, and design tools are also included on the CD-ROM.

"PI Expert now allows designers of higher wattage power supplies to reduce their design time from days to minutes," stated Robert Mayell, Power Integrations’ Director of Application Engineering. "This should be a valuable tool for engineers designing power supplies for set-top boxes, LCD monitors, laptop computers, or other high power applications."

PI Expert is offered free of charge and is available immediately through the company’s network of worldwide sales representatives. It can also be directly requested and downloaded from the company's web site at www.powerint.com.
