Description
The MP6908L is a low-drop diode emulator IC. When combined with an external switch, the MP6908L can replace Schottky diodes in high-efficiency flyback converters. The MP6908L regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, then switches off once the voltage becomes negative.
The MP6908L can generate its own supply voltage for battery charging applications that can have low output voltage or short-circuit output conditions, as well as high-side SR configuration. Configurable ringing detection circuitry prevents the MP6908L from false turn-off after VDS oscillates in discontinuous conduction mode (DCM), or during quasi-resonant operation.
The MP6908L is available in a space-saving TSOT23-6 package.
