APR34509 Overview
The APR34509 is a secondary side bo IC, which bines an NChannel MOSFET and a driver circuit designed for synchronous rectification (SR), supports CCM, DCM and Quasi-Resonant Flyback Topologies. The N-Channel MOSFET has been optimized for low gate charge, low RDS(ON), fast switching speed and body diode reverse recovery performance. The synchronous rectification can effectively reduce the secondary side rectifier...
