WS3231 Overview
WS3231 is a high PF primary-side feedback and regulation controller for LED lighting, optimized for flyback converter with the output power less than 30W. Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated. And WS3231 does not need the auxiliary winding for sensing the output current and supplying the chip.
