Introduction

AI Translation

SY5238 is a Flyback SR controller compatible with QR IC to achieve ZVS operation. The primary side PWM IC must work in quasi resonant mode. SY5238 adopts proprietary operation mode to achieve flyback ZVS turn on, which greatly improves Flyback efficiency and power density. SY5238 also adopts adaptive gate voltage control for safe operation.
