APR34150MTR-G1

APR34150 SECONDARY SIDE SYNCHRONOUS RECTIFICATION SWITCHER Description Pin Assignments APR34150 is a secondary side Combo IC, which combines an NChannel MOSFET and a driver circuit designed for synchronous rectification (SR) in DCM operation. (Top View) NEW PRODUCT 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 AREF 3 6 GND VCC 4 5 GND The synchronous rectification can effectively reduce the secondary side rectifier power dissipation and provide high performance solution. By sensing MOSFET drain-to-source voltage, APR34150 can output ideal drive signal with less external components. It can provide high performance solution for 5V output voltage application. The APR34150 is available in SO-8 package. SO-8 Applications Features • Synchronous Rectification for DCM Operation Flyback • Eliminate Resonant Ring Interference • Fast Detector of Supply Voltages • Fewest External Components   • • Adapters/Chargers for Cell/Cordless Phones, ADSL Modems, MP3 and Other Portable Apparatus Standby and Auxiliary Power Supplies Totally Lead-free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Notes: 1.
