    SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER Description
    APR343 is a secondary side MOSFET driver for synchronous rectification in DCM operation, which integrates the output voltage detection function for primary side control system. The synchronous rectification can effectively reduce the secondary side rectifier power dissipation and provide high performance solution. By sensing MOSFET drain-to-source voltage, APR343 can output ideal drive signal with less external components. It can provide high performance solution for 5V output voltage application. Same as AP4341, APR343 detects the output voltage and provides a periodical signal when the output voltage is lower than a certain threshold. By fast response to secondary side voltage, APR343 can effectively improve the transient performance of primary side control system. The APR343 is available in SOT25 package. Pin Assignments
