MP6909

MP6909

Fast Turn-Off Intelligent Rectifier with Turn On Slew Rate Detection

Datasheet

概要

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 via an internal linear regulator. Programmable ringing detection circuitry prevents the MP6909 from turning on falsely at V_DS oscillations during discontinuous conduction mode (DCM) and quasi-resonant operation.

The MP6909 is available in a space-saving TSOT23-6 package.
