Select by type
Active-clamp forward

This simple, isolated DC/DC topology offers zero-voltage switching for high efficiency and power levels up to 400 W.

Push-pull

This flexible topology is typically used in power levels from as little as 1 W to 500 W.

General-purpose PWM

PWM controllers are simple, fixed frequency control ICs that can be used to control almost any power topology including flyback, boost, push-pull, forward, buck and more.

Half-bridge

Select these controllres for applications up to 500 W with higher VIN for your design.

Full-bridge    

This double-ended topology is typically used in applications from 200 W to 2 kW.

Phase-shifted full bridge

This double-ended topology with zero-voltage switching is typically used in applications from 200 W to 2 kW.
