MP9989 CCM/DCM Flyback Ideal Diode with Integrated 100V / 10m MOSFET and No Need for Auxiliary Winding DESCRIPTION FEATURES The MP9989 is a fast turn-off, intelligent rectifier Integrated 100V/10m MOSFET for flyback converters that integrates a 100V Wide Output Range down to 0V MOSFET. It can replace a diode rectifier for No Need for Auxiliary Winding for High-Side higher efficiency and power density. The chip or Low-Side Rectification regulates the forward voltage drop of the internal Ringing Detection Prevents False Turn-On (1) power switch to 40mV and turns off before the during DCM Operations drain-source voltage reverses. Compatible with Energy Star 110A Quiescent Current The MP9989 can generate its own supply voltage without the need for auxiliary winding, Supports DCM, CCM, and Quasi-Resonant Operations which makes it suitable for charger applications with a low output voltage requirement or any Available in SOIC-8 and QFN4x5-8 other adaptor applications with high-side set-up. Packages The internal ringing detection circuitry prevents APPLICATIONS the MP9989 from falsely turning on during discontinuous conduction mode (DCM) or quasi- Laptop Adapters resonant operations. QC and USB PD Charger High-Efficiency Flyback Converters The MP9989 is available in SOIC-8 and QFN4x5-8 packages. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
