Flyback controllers

Achieve enhanced efficiency, EMI and standby power.

Our flyback solutions enable you to design smaller power supplies with higher efficiency. With our years of experience, we are able to provide reliable and innovative products that are around for the long run. From consumer electronics to automotive applications and everything in between, we have a flyback solution that meets your needs.

Active-clamp & ZVS flyback controllers

Our flybacks feature a dissipative clamp replaced with lossless active clamp, which is used to achieve zero-voltage switching (ZVS).

Fixed-frequency flyback controllers

Our fixed frequency flyback 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 many more.

Offline flyback converters

Our offline flyback converters have a 700-V integrated FET and can be configured as a flyback or a high-voltage buck converter.
