MP6908 Fast Turn-Off Intelligent Rectifier with No Need for Auxiliary Winding The Future of Analog IC Technology DESCRIPTION FEATURES The MP6908 is a low-drop diode emulator IC Wide Output Range down to 0V, No Short that, when combined with an external switch, Circuit Current Flows through Body Diode replaces Schottky diodes in high-efficiency No Need for Auxiliary Winding for High-Side flyback converters. The MP6908 regulates the or Low-Side Rectification forward drop of an external synchronous Ringing Detection Prevents False Turn-On rectifier (SR) MOSFET to about 40mV, which during DCM and Quasi-Resonant switches off once the voltage becomes negative. Operations Works with Standard and Logic Level SR The MP6908 can generate its own supply MOSFETS voltage for battery charging applications with Compatible with Energy Star potential low output voltage, and at short circuit ~30ns Fast Turn-Off and Turn-On Delay output condition, or for high-side SR ~100A Quiescent Current configuration. Programmable ringing detection circuitry prevents the MP6908 from turning on Supports DCM, CCM, and Quasi-Resonant falsely at Vds oscillations during discontinuous Operations conduction mode (DCM) and quasi-resonant Supports both High-Side and Low-Side operation. Rectification TSOT23-6 Package Available The MP6908 is available in a space-saving TSOT23-6 package.
