Preliminary
HIGH PERFORMANCE SYNCHRONOUS RECTIFIER
DESCRIPTION
UTC USR5V10X is a high performance and tightly integrated secondary side synchronous rectifier for switch mode power supply system. It combines a much lower voltage drop N-channel MOSFET to emulate the traditional diode rectifier at the secondary side of Flyback converter, which can reduce heat dissipation, increases output current capability and efficiency and simplify thermal design.
It is suitable for multiple mode applications including discontinuous conduction mode and quasi-resonant mode. With its versatility and optimization, UTC USR5V10X can be used in various switch mode power supply topologies including secondary-side control topology and primary-side control topology.
