APR3415BMTR-G1

A Product Line of Diodes Incorporated APR3415B SECONDARY SIDE SYNCHRONOUS RECTIFICATION SWITCHER Description Pin Assignments NEW PRODUCT 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. (Top View) The N-Channel MOSFET has been optimized for low gate charge, low RDS(ON), fast switching speed and body diode reverse recovery performance. DRISR 1 8 DRAIN VDET 2 7 DRAIN 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 components. It can provide high performance solution for 5V output voltage application. AREF 3 6 GND VCC 4 5 GND Same as AP4341, APR3415B 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, APR3415B can effectively improve the transient performance of primary side control system. SO-8 Applications • The APR3415B is available in SO-8 package.
