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 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.
