APR3415B SECONDARY SIDE SYNCHRONOUS RECTIFICATION SWITCHER Description APR3415B is a secondary side Combo IC, which combines an NChannel MOSFET and a driver circuit designed for synchronous rectification (SR) in DCM operation.
It also integrates output voltage detect function for primary side control system.
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 power dissipation and provide high performance solution.
By sensing MOSFET drain-to-source voltage, APR3415B can output ideal drive signal with less external component...
