SYNCHRONOUS RECTIFIER
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. Efficiency increased by 2%~5% and temperature decreased by up to 50% compared with normal Schottky Barrier Diode, or more than 2% efficiency increase and 20% temperature decrease compared with low VF diode.
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
