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
