Integrated 400V/1A Power MOSFET

Very few external components, no detecting AC Input

Excellent system synchronization performance

Built-in limiting voltage circuit for wider operation range

Isolated and Non-isolated Applications

The WS9911 is an AC ON/OFF adjusting color temperature controller for LED Lighting. It integrates 400V/1A Power MOSFET and simplifies the external circuit structure. It also ensures the logical consistency in multiple power applications at the same time.

In order to expand the application field, the WS9911 can be used in the isolated flyback, Buck or Buck-Boost structure to facilitate the power supply design.

The WS9911 is available in SOP8 Package.
