USR5VA10 - SYNCHRONOUS RECTIFIER

General Description

UTC USR5VA10 is a synchronous rectifying IC with 20mΩ/45V NMOS and synchronous rectification control IC integrated.

It is suitable for flyback switch mode power supply of up to 5V/2A.

Key Features

  • High efficiency, Low temperature.
  • Synchronous rectification, support DCM and QR mode flyback system.
  • Internal integrated 20mΩ/45V NMOS.
  • Self-power supply design, no need for external power supply.
  • Self-detection, no need for external synchronous signal.
  • Only 3 poles (VCC-K-A), can directly replace Schottky Barrier Diode.
