To meet increased power efficiency demands and regulatory standards for desktop PCs, All-in-One PCs and notebook adaptors, Fairchild Semiconductor has developed the FAN6204 secondary-side synchronous rectification (SR) controller that increases power efficiency while integrating more functions.
Using a proprietary linear prediction timing-control technique, not limited to the RDS(ON) of the SR MOSFET, the FAN6204 is suitable for fixed frequency or quasi-resonant (QR) flyback converters and discontinuous or continuous conduction mode (DCM and CCM) operation. This technique includes a simple control method without current-sense circuitry, which provides better noise immunity.
