MP6907

Fast Turn-off Flyback

Synchronous Rectifier

that Supports CCM, DCM

and QR Operation Modes

DESCRIPTION

FEATURES

The MP6907 is a low-drop diode emulator

controller IC that, when combined with an

external MOSFET, can replace Schottky diodes

in high-efficiency flyback converters. The

MP6907 regulates the forward drop of an

external switch to about 70mV, which switches

off once the voltage becomes negative.



Works with 12V Standard and 5V Logic

Level MOSFETS

Compatible with Energy Star 1W Standby

Requirements

Fast Turn-Off Total Delay of 25ns

4.2V~35V Wide VDD Operating Range

~150μA Quiescent Current in Light-Load

Mode⁽¹⁾

Supports CCM, DCM, and Quasi-Resonant

Operation



The MP6907 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 can reduce the IC’s quiescent

current to ~150μA.



SYNC Interface for CCM Operation

Supports

High-Side

and

Low-Side

Rectification



Power Savings of up to 1.5W in a Typical

Notebook Adapter

Available in SOIC8 and TSOT23-6

Packages

The MP6907 is available in compact SOIC8

and TSOT23-6 packages.

APPLICATIONS



Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

Flyback Converters
