MPS MP6908LGJ-Z

次级侧控制器，同步整流器4V ~ 13V2.9 mA

Overview

The MP6908GJ-Z is a low-drop diode emulator IC that, when combined with an external switch, replaces Schottky diodes in high-efficiency flyback converters. The MP6908GJ-Z regulates the forward drop of an external synchronous rectifier (SR) MOSFET to about 40mV, which switches off once the voltage becomes negative. The MP6908GJ-Z can generate its own supply voltage for battery charging applications with potential low output voltage, and at short circuit output condition, or for high-side SR configuration. Programmable ringing detection circuitry prevents the MP6908GJ-Z from turning on falsely at Vds oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation. The MP6908GJ-Z is available in a space-saving TSOT23-6 package.
