CT5702B Datasheet

The CT5702B is a synchronous rectifier for Flyback converters. It integrates a 40V power MOSFET, that can replace Schottky diode for high efficiency

The CT5702B have multi-protection functions which largely enhance the safety and reliability of the system.

The CT5702B is available in SOP-8 package.
