MP9989GV - CCM/DCM Flyback Ideal Diode

Download the MP9989GV datasheet PDF. This datasheet also covers the MP9989 variant, as both devices belong to the same ccm/dcm flyback ideal diode family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP9989 is a fast turn-off, intelligent rectifier for flyback converters that integrates a 100V MOSFET.

It can replace a diode rectifier for higher efficiency and power density.

Key Features

  • Integrated 100V/10mΩ MOSFET.
  • Wide Output Range down to 0V.
  • No Need for Auxiliary Winding for High-Side or Low-Side Rectification.
  • Ringing Detection Prevents False Turn-On during DCM Operations.
  • Compatible with Energy Star.
  • 110µA Quiescent Current.
  • Supports DCM, CCM, and Quasi-Resonant Operations.
  • Available in SOIC-8 and QFN4x5-8 Packages.

MP9989 CCM/DCM Flyback Ideal Diode with Integrated 100V/10mΩ MOSFET and No Need for Auxiliary Winding DESCRIPTION The MP9989 is a fast turn-off, intelligent rectifier for flyback converters that integrates a 100V MOSFET. It can replace a diode rectifier for higher efficiency and power density. The chip regulates the forward voltage drop of the internal power switch to 40mV(1) and turns off before the drain-source voltage reverses. The MP9989 can generate its own supply voltage without the need for auxiliary winding, which makes it suitable for charger applications with a low output voltage requirement or any other adaptor applications with high-side set-up.
