SYNCHRONOUS RECTIFIERR
* High efficiency, Low temperature
* Synchronous rectification, support DCM and QR mode flyback system
* Internal integrated 20mΩ/45V NMOS
* Self-power supply design, no need for external power supply
* Self-detection, no need for external synchronous signal
* Only 3 poles (VCC-K-A), can directly replace Schottky Barrier
