MP6976

High-Frequency, CCM/DCM Flyback Ideal

Diode with Integrated 100V/10mΩ MOSFET

and No Auxiliary Winding Requirement

DESCRIPTION

FEATURES

The MP6976 is a fast turn-off, intelligent rectifier

for flyback converters that integrates

•

Integrated 100V/10mΩ MOSFET

Wide Output Voltage (V_OUT) Range Down to

No Need for Auxiliary Winding for High-Side

(HS) or Low-Side (LS) Rectification

Ringing Detection Prevents False Turn-On

during Discontinuous Conduction Mode

(DCM)

100V/10mΩ MOSFET. It can replace a diode

rectifier for higher efficiency and power density.

The chip regulates the internal power MOSFET’s

forward voltage drop (V_FWD) to 40mV ⁽¹⁾and turns

off before the drain-to-source voltage (V_DS)

reverses.

•

Compatible with Energy Star

110µA Quiescent Current (I_Q(VDD)

Supports DCM, Continuous Conduction

Mode (CCM), and Quasi-Resonant (QR)

Operation

The MP6976 can generate its own supply

voltage without the need for auxiliary winding,

which makes it suitable for charger applications

with a low output voltage (V_OUT), or for high-side

(HS) adapter applications. The internal ringing

detection circuitry prevents the MP6976 from

falsely turning on during discontinuous

conduction mode (DCM) or quasi-resonant (QR)

operations.
