Applications Note: SY50103 Flyback Regulator With Primary Side CV/CC Control For Adapters and Chargers Preliminary Specification General Description SY50103 is a PWM controller with several Features to enhance performance of Flyback converters. It integrates a 600V MOSFET to decrease physical volume. Both current and voltage regulation are achieved by primary side control technology for low cost application. To achieve higher efficiency and better EMI performance, SY50103 drives Flyback converters in the Quasi-Resonant mode.
