FAN6224 Overview
FAN6224 is a secondary-side Synchronous Rectification (SR) controller to drive SR MOSFET for improved efficiency. The IC is suitable for flyback converters and forward freewheeling rectification. FAN6224 can be applied in Continuous or Discontinuous Conduction Mode (CCM and DCM) and Quasi-Resonant (QR) flyback converters based on a proprietary linear-predict timing-control technique.
