SC3503 Datasheet (SOUTHCHIP) - Fast Turn-Off Synchronous Rectifier Controller

SC3503, Fast Turn-Off Synchronous Rectifier Controller

SC3503 is a smart secondary-side driver IC designed to drive N-Channel power MOSFET used as synchronous rectifiers in isolated flyback converters.

The MOSFET can replace Schottky diode so the system can achieve higher efficiency and superior heat dissipation performance.
