MP6900

Fast Turn-off Intelligent Rectifier for Flyback

Newer version available

Datasheet

Description

The MP6900 is a low-drop, fast turn-off intelligent controller that combined with an external switch replaces Schottky diodes in high-efficiency, Flyback converters. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. Package choices are a space saving TSOT23-5, QFN6 (3x3mm) or SOIC-8.

Features & Benefits

Works with both Standard and Logic Level FETS
Compatible with Energy Star, 1W Standby Requirements
VDD Range From 8V to 24V
Fast Turn-off Total Delay of 20ns
Max 400kHz Switching Frequency
Supports CCM, DCM and Quasi-Resonant Topologies
Supports High-side and Low-side Rectification
Power Savings of Up to 1.5W in a Typical Notebook Adapter
