Product Description

The MP6900 is a low-drop, fast turn-off intelligent controller 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, QFN6 (3x3mm) or SOIC-8.
