产品描述

The MP6909 is a low-drop diode emulator IC that, when combined with an external switch, replaces Schottky diodes in high-efficiency flyback converters. The MP6909 regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage becomes negative.

The MP6909 can generate its own supply voltage by internal linear regulator. Programmable ringing detection circuitry prevents the MP6909 from turning on falsely at VDS oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation.

EV6909-S-00A is the evaluation board for MP6909.
