DC-DC Power Switch ICs

Power Switch ICs for Load, Current and USB Port Power

Power switch Integrated Circuits (ICs) manage power rails by creating an electrical connection from the source to the load in a circuit. Power switches are simple in concept but provide a variety of functions and benefits to an electrical system such as power distribution, power savings and even charge emulation in USB port power applications. More commonly, you can use power switches to provide protection against over-voltage, over-current and short-circuit occurrences.

Our power switch ICs cover multiple topologies and offer all the protection needed to ensure optimal operating conditions for many systems. Our power switch portfolio is primarily broken up into load switches, current limit switches and USB port power controllers to meet the variety of challenges that you might face in your application spaces, ranging from mobile POS systems to automotive USB breakout boxes and everything in between.
