MP6908A Fast Turn-Off Intelligent Rectifier with No Need for Auxiliary Winding DESCRIPTION FEATURES The MP6908A is a low-drop diode emulator IC Supports DCM, CCM, Quasi-Resonant that, when combined with an external switch, Operations and Active Clamp Flyback replaces Schottky diodes in high-efficiency Supports up to 600kHz Switching flyback converters. The MP6908A regulates the Frequency forward drop of an external synchronous Wide Output Range down to 0V, No Short rectifier (SR) MOSFET to about 40mV, which Circuit Current Flows through Body Diode switches off once the voltage becomes negative. No Need for Auxiliary Winding for High-Side or Low-Side Rectification The MP6908A can generate its own supply Ringing Detection Prevents False Turn-On voltage for battery charging applications with a during DCM and Quasi-Resonant potential low output voltage. The MP6908A can Operations also generate this voltage at short-circuit output Works with Standard and Logic Level SR conditions or high-side SR configurations. MOSFETs Programmable ringing detection circuitry Compatible with Energy Star Standards prevents the MP6908A from turning on falsely at V oscillations during discontinuous ~30ns Fast Turn-Off and Turn-On Delay DS conduction mode (DCM) and quasi-resonant ~100A Quiescent Current operation. Supports both High-Side and Low-Side Rectification The MP6908A is available in a space-saving Available in a TSOT23-6 Package TSOT23-6 package.
