EV6908-S-01A

Evaluation board for MP6908 low-drop diode emulator IC. When combined with an external switch, MP6908 replaces schottky diodes in high-efficiency flyback converters. The MP6908 regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage becomes negative. The MP6908 can generate its own supply voltage for battery charging applications with a low output voltage or high-side rectification applications. Programmable ringing detection circuitry prevents the MP6908 from turning on falsely during discontinuous conduction mode (DCM) and quasi-resonant operation. Typical applications include USB PD quick chargers, adapters, flyback power supplies with very low and/or variable output voltages.
