Overview

This is a simple, high-efficiency synchronous rectification IC featuring only two pins — A (Anode) and K (Cathode) — corresponding to the anode and cathode of a Schottky diode. The IC integrates an internal 45V power NMOS transistor to significantly reduce diode conduction losses and improve overall system efficiency, making it a drop-in replacement for equivalent Schottky rectifier diodes on the market. The device is offered in an SM-7 package (compatible with TO-277).

Applications

  • USB charger
  • Adapter
  • LED driver

Key features

  • Flyback primary-side feedback applications
  • Ultra-low forward voltage drop
  • Ultra-low temperature rise
  • Integrated 45V, 20mΩ power NMOS
  • Supports DCM and quasi-resonant mode operation
  • Self-powered, no external power supply required
  • Intelligent detection system, no front-end sync signal required
  • Improved EMI performance
  • Direct drop-in replacement for Schottky diodes
