FAN6204A Description

FAN6204A  is  a  secondary-side  synchronous rectification (SR) controller to drive SR MOSFET for improving efficiency. The IC is suitable for flyback converters and forward free-wheeling rectification. FAN6204A  can  be  applied  in  continuous  or discontinuous conduction mode (CCM and DCM) and quasi-resonant (QR) flyback converters based on the proprietary  innovative  linear-predict  timing-control technique. The benefits of this technique include a simple control method without current-sense circuitry to

accomplish noise immunity. With PWM frequency tracking and secondary-side winding voltage detection, FAN6204A can operate in both fixed- and variable-frequency systems. In Green Mode, the SR controller stops all SR switching operation to reduce the operating current. Power consumption is maintained at minimum level in light-load condition.
