Power Integrations Introduces the TOPSwitch-FX Conversion IC

March 26, 2000 by Jeff Shepard

Power Integrations Inc. (Sunnyvale, CA) introduced its patented TOPSwitch-FX family, expanding its offerings of power-conversion ICs. The TOPSwitch-FX is intended to offer engineers the flexibility to design highly integrated power supplies. In addition, it incorporates the company's energy-saving EcoSmart technology to help engineers meet the growing need for environmentally friendly power solutions.

The new devices deliver up to 75W of power for use in diverse markets such as cellular phones, personal computers, set-top boxes, printers, DVDs and LCD monitors. The TOPSwitch-FX family includes several features that, according to Power Integrations, significantly reduce energy consumption, especially in standby and no-load conditions. These include remote on/off, cycle-skipping and half-frequency option. A unique remote on/off function can shut off the power to the product when it is not in use.

The TOPSwitch-FX is supported by a comprehensive suite of design tools available from the company's website. A Design Accelerator Kit (DAK-8), consisting of a 30W power-supply prototype board, samples and full documentation, may be requested through the website.

"Technical innovations embodied in the TOPSwitch-FX enable cost-effective integration of functions that have been on these engineers' wish-lists for years," stated Balu Balakrishnan, vice president of engineering and strategic marketing. He added, "Engineers are under continuous pressure to design smaller, better and lower-cost power supplies, and TOPSwitch-FX ICs will help them do this, but with a new level of design flexibility. In addition, our EcoSmart energy saving features allow these engineers to cost-effectively meet pressing demands for more environmentally friendly or greener electronic products."

The TOPSwitch-FX family is in production and currently consists of the TOP232, TOP233 and TOP234. Devices are available in a five-pin TO-220, a plastic DIP and a surface-mount package. Unit pricing in quantities of 10,000 range from $1.06 to $1.54 for the smallest to the largest member in the family.
