The CT5712B is a synchronous rectifier for Flyback converters. It integrates a 40V power MOSFET, that can replace Schottky diode for high efficiency. It can power directly from Vout, the VDD Cap. is optional to save system cost.
The CT5712B have multi-protection functions which largely enhance the safety and reliability of the system. The CT5712B is available in SOP-8 package.
