WS3252 Datasheet (WINSEMI) - High Precision CC/CV Primary-Side PWM Controller

WS3252, High Precision CC/CV Primary-Side PWM Controller

WS3252 is a high-integrated offline PWM controller, optemized for high poformance low power AC/DC charger and adapter adapter application.

WS3252 operates in primary-side sensing and regulation.

Consequently, opto-coupler and TL431 could be eliminated, thus reduce the cost.

It can achieve ± 5% const
