MP6919 CCM/DCM Flyback Ideal Diode with Integrated 100V/13m MOSFET and No Need for Auxiliary Winding DESCRIPTION FEATURES The MP6919 is a fast turn-off, intelligent rectifier Integrated 100V/13m MOSFET for flyback converters that integrates a 100V Wide Output Range Down to 0V MOSFET. It offers higher efficiency and power Does not Require Auxiliary Winding for density than a diode rectifier. The chip High-Side or Low-Side Rectification regulates the forward voltage drop of the Ringing Detection Prevents False Turn-On (1) internal power switch to 40mV , and turns off during DCM Operations before the drain-source voltage reverses. Compatible with Energy Star 110A Quiescent Current The device generates its own supply voltage Supports DCM, CCM, and Quasi-Resonant without requiring auxiliary winding. This feature Operations makes it suitable for charger applications with a low output voltage requirement, or any other Available in an SOIC-8 Package adapter applications with high-side set-up. The APPLICATIONS internal ringing detection circuitry prevents the MP6919 from falsely turning on during Laptop Adapters discontinuous conduction mode (DCM) or QC and USB PD Chargers quasi-resonant operations. High-Efficiency Flyback Converters The MP6919 is available in an SOIC-8 package. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
