MP6901
Active
High Noise Immunity, Fast Turn-off Intelligent Rectifier for Flyback
Product 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.
