DESCRIPTION

The MP6908 is a low-drop diode emulator IC

that, when combined with an external switch,

replaces Schottky diodes in high-efficiency

flyback converters. The MP6908 regulates the

forward

drop

of

an

external

synchronous

rectifier (SR) MOSFET to about 40mV, which

switches off once the voltage becomes negative.

The MP6908 can generate its own supply

voltage for battery charging applications with a

low output voltage or high-side rectification

applications. Programmable ringing detection

circuitry prevents the MP6908 from turning on

falsely during discontinuous conduction mode

(DCM) and quasi-resonant operation.

EV6908-S-01A is the evaluation board for

MP6908.

FEATURES

 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

and

Quasi-Resonant

Operations

 Works with Standard and Logic Level SR

MOSFETs

 Compatible with Energy Star

 ~30ns Fast Turn-Off and Turn-On Delay

 ~100µA Quiescent Current

 Supports DCM, CCM, and Quasi-Resonant

Operations

 Supports both High-Side and Low-Side

Rectification

 TSOT23-6 Package Available

APPLICATIONS

 USB PD Quick Chargers

 Adaptors

 Flyback Power Supplies with Very Low

and/or Variable Output Voltage
