EV6908-S-01A High Efficiency Synchronous Rectification EV Board The Future of Analog IC Technology FEATURES DESCRIPTION Wide Output Range down to 0V The MP6908 is a low-drop diode emulator IC No Need for Auxiliary Winding for High-Side that, when combined with an external switch, or Low-Side Rectification replaces Schottky diodes in high-efficiency Ringing Detection Prevents False Turn-On flyback converters. The MP6908 regulates the during DCM and Quasi-Resonant forward drop of an external synchronous Operations rectifier (SR) MOSFET to about 40mV, which Works with Standard and Logic Level SR switches off once the voltage becomes negative. MOSFETs The MP6908 can generate its own supply Compatible with Energy Star voltage for battery charging applications with a ~30ns Fast Turn-Off and Turn-On Delay low output voltage or high-side rectification ~100A Quiescent Current applications. Programmable ringing detection Supports DCM, CCM, and Quasi-Resonant circuitry prevents the MP6908 from turning on Operations falsely during discontinuous conduction mode Supports both High-Side and Low-Side (DCM) and quasi-resonant operation. Rectification EV6908-S-01A is the evaluation board for TSOT23-6 Package Available MP6908.
