MP6908AGJ Overview
The MP6908A is a low-drop diode emulator IC that, when bined with an external switch, replaces Schottky diodes in high-efficiency flyback converters. The MP6908A regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage bees negative. The MP6908A can generate its own supply voltage for battery charging applications with a potential low output...
