Power management

Make every watt count using our isolated controllers and converters

Maximize power conversion with our comprehensive portfolio

We offer the industry’s most comprehensive portfolio of high-performance AC-DC, isolated DC-DC controllers & converters with the widest range of power topology options. Our devices help you to innovate and differentiate your power supply design to deliver high efficiency, high power density and high performance isolated power conversion.

AC/DC solutions

Maximize your AC/DC power factor and conversion efficiency with the smallest possible size using high performance PFC and flyback ICs.

Isolated DC/DC solutions

Maximize your power density with our easy-to-use active clamps, push-pull, LLC, half-bridge, full bridge, phase shifted full bridge, flybacks, and general purpose PWM controllers serving a wide power range.

Improve the performance of your AC/DC design

The UCC28056, UCC256403, and UCC24624 eliminate the need for an auxiliary flyback by achieving low standby power consumption.  Along with other features, such as excellent audible noise performance, we enable you to improve your AC/DC design to do more with less.  See how with our reference design and test for yourself on our EVM.
