EV6919-S-00A Monolithic Power Systems

EV6919-S-00A High Efficiency Synchronous Rectification EV Board DESCRIPTION FEATURES The MP6919 is a fast turn-off, intelligent rectifier Integrated 100V/13m MOSFET for flyback converters that integrates a Wide Output Range down to 0V 100V/13m MOSFET. It can replace a diode No Need for Auxiliary Winding for High-Side rectifier for higher efficiency and power density. or Low-Side Rectification The chip regulates the forward voltage drop of Ringing Detection Prevents False Turn-On the internal power switch to 40mV and turns off during DCM Operations before the drain-source voltage reverses. Compatible with Energy Star Supports DCM, CCM, and Quasi-Resonant The MP6919 can generate its own supply Operations voltage without the need for auxiliary winding, which makes it suitable for charger applications APPLICATIONS with a low output voltage requirement or any Laptop Adapters other adaptor applications with high-side set-up. QC and USB PD Charger The internal ringing detection circuitry prevents the MP6919 from falsely turning on during High-Efficiency Flyback Converters All MPS parts are lead-free, halogen free, and adhere to the RoHS discontinuous conduction mode (DCM) or directive. For MPS green status, please visit MPS website under Quality quasi-resonant operations. Assurance.
