MP6902A

Fast Turn-Off Intelligent Controller

DESCRIPTION

FEATURES

The MP6902A is a low-drop diode emulator IC

for flyback converters, which replaces Schottky

rectification diodes to achieve high efficiency

when combined with an external switch.



Supports CCM, DCM and Quasi-Resonant

Flyback Converters

Works with 12V Standard and 5V Logic

Level MOSFETs

Compatible with Energy Star, 1W Standby

Requirements

V_DDRange from 8V to 24V

The MP6902A regulates the forward drop of an

external switch to about 70mV and switches it

off as soon as the voltage becomes negative.

The MP6902A has a light-load sleep mode that

reduces the quiescent current to 300µA.



70mV V_DSRegulation Function⁽¹⁾

Fast Turn-Off Total Delay of 20ns

Max 400kHz Switching Frequency

Light-Load Mode Function⁽¹⁾with 300μA

Quiescent Current



Supports High-Side and Low-Side

Rectification

Power Savings of Up to 1.5W in a Typical

Notebook Adapter

Available in a TSOT23-6 Package

APPLICATIONS



Industrial Power Systems
