SYNCHRONOUS RECTIFIER
CMOS IC
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 su...
