MP6908L

Fast Turn-Off Intelligent Rectifier

with No Auxiliary Winding Requirement

DESCRIPTION

FEATURES

The MP6908L is a low-drop diode emulator IC.

When combined with an external switch, the

MP6908L can replace Schottky diodes in high-

efficiency flyback converters. The MP6908L

regulates the forward drop of an external

synchronous rectifier (SR) MOSFET to about

40mV, then switches off once the voltage

becomes negative.



Wide Output Voltage Range Down to 0V,

No Short-Circuit Current Flows through the

Body Diode

Auxiliary Winding for High-Side or Low-Side

Rectification is Not Required

Ringing Detection Prevents False Turn-On

in 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



The MP6908L can generate its own supply

voltage for battery charging applications that

can have low output voltage or short-circuit

output conditions, as well as high-side SR

configuration. Configurable ringing detection

circuitry prevents the MP6908L from false turn-

off after V_DSoscillates in discontinuous

conduction mode (DCM), or during quasi-

resonant operation.



Supports DCM, CCM, and Quasi-Resonant

Operation

Supports Both High-Side and Low-Side

Rectification



Available in a TSOT23-6 Package

The MP6908L is available in a space-saving

TSOT23-6 package.

APPLICATIONS



USB PD Quick Chargers

Adapters

Flyback Power Supplies with Very Low

and/or Variable Output Voltages
