DESCRIPTION The MP6908A is a low-drop diode emulator IC that, when combined 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 becomes negative. The MP6908A can generate its own supply voltage for battery charging applications with a potential low output voltage. The MP6908A can also generate this voltage at short-circuit output conditions or high-side SR configurations. Programmable ringing detection circuitry prevents the MP6908A from turning on falsely at VDS oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation. The MP6908A is available in a space-saving TSOT23-6 package.
