APR3415
SECONDARY SIDE SYNCHRONOUS RECTIFICATION SWITCHER
Description
APR3415 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, APR3415 can output
ideal drive signal with less external components. It can provide high
performance solution for 5V output voltage application.
Same as AP4341, APR3415 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, APR3415 can
effectively improve the transient performance of primary side control
system.
The APR3415 is available in SO-8 package.
