EV9989-S-00A

EV9989-S-00A High Efficiency Synchronous Rectification EV Board FEATURES DESCRIPTION Integrated 100V/10m MOSFET The MP9989 is a fast turn-off, intelligent rectifier Wide Output Range down to 0V for flyback converters that integrates a 100V No Need for Auxiliary Winding for High-Side MOSFET. It can replace a diode rectifier for or Low-Side Rectification higher efficiency and power density. The chip Ringing Detection Prevents False Turn-On regulates the forward voltage drop of the during DCM Operations internal power switch to 40mV and turns off Compatible with Energy Star before the drain-source voltage reverses. Supports DCM, CCM, and Quasi-Resonant The MP9989 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 High-Efficiency Flyback Converters the MP9989 from falsely turning on during All MPS parts are lead-free, halogen free, and adhere to the RoHS discontinuous conduction mode (DCM) or directive.
