AN8104

AN8104 is a new generation of synchronous rectifier (SR) controller ICs for switching mode power supplies. It can replace the secondary diode for maximum efficiency at any load. The AN8104 is a dedicated controller IC for synchronous rectification on the secondary side of flyback converters. It incorporates the SR MOSFET, which is rectifying the output of the secondary transformer winding.
