MP6906 - Fast Turn-Off Intelligent Rectifier

Datasheet Summary

Description

The MP6906 is a low-drop diode emulator IC that combines an external switch to replace Schottky diodes in high-efficiency flyback converters.

The chip regulates the forward drop of an external switch to about 30mV and switches it off as soon as the voltage becomes negative.

Features

  • Works with 12V Standard and 5V Logic Level FETS.
  • Fast Turn-Off Total Delay of 25ns.
  • 4.2V~35V Wide VDD Operating Range.
  • 30mV VDS Regulation Function (1).
  • 150µA Quiescent Current in Light-Load Mode (1).
  • Supports DCM and Quasi-Resonant Operation.
  • SYNC Interface for CCM Operation.
  • Supports High-side and Low-side Rectification.
  • Power Savings of up to 1.5W in a Typical Notebook Adapter.
  • SOIC-8 and TSOT23-6 Packages.

MP6906 Fast Turn-Off Intelligent Rectifier with Very Low Voltage Forward Regulation The Future of Analog IC Technology DESCRIPTION The MP6906 is a low-drop diode emulator IC that combines an external switch to replace Schottky diodes in high-efficiency flyback converters. The chip regulates the forward drop of an external switch to about 30mV and switches it off as soon as the voltage becomes negative. The MP6906 provides a SYNC interface to receive an external signal to shut down the gate driver for reliable continuous conduction mode (CCM) operation. A programmable light-load sleep mode reduces the IC’s quiescent current to 150µA. Also, it has a low UVLO level for operation at a lower output without an additional winding.
