MP6901

High Noise Immunity, Fast Turn-off Intelligent Rectifier for Flyback

Datasheet

Description

The MP6901 is a Low-Drop Diode Emulator IC that, combined with an external switch replaces Schottky diodes in high-efficiency, Flyback converters. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. Package choices are a space saving TSOT23-5 or SOIC-8.

Evaluation Tools

EV6902A+MP6907-S_J-00A Evaluation Kit High Efficiency Synchronous Rectification EV Board

The EV6902A+MP6907-S_J-00A is an evaluation board for the MP6902A and MP6907. It is configured to provide synchronous rectification solution for flyback.

MP6902A and MP6907 features a synchronous gate output which enables high efficiency rectification by replacing the schottky rectifier with a low Ron MOSFET. MP6907 has the wider VDD range and stronger driving capability than MP6902A.
