APR3415C中文资料Secondary Side Synchronous Rectification Switcher数据手册Diodes规格书

描述 Description

APR3415C is a secondary side Combo IC, which combines an N-Channel 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, APR3415C can output ideal drive signal with less external components. It can provide high performance solution for 5V output voltage application.
Same as AP4341, APR3415C 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, APR3415C can effectively improve the transient performance of primary side control system.
The APR3415C is available in SO-8 package.
