Diodes Incorporated

ZXGD3105N8

SYNCHRONOUS MOSFET CONTROLLER IN SO-8

Description

Features

ZXGD3105N8 synchronous controller is designed for driving a

MOSFET as an ideal rectifier. This is to replace a diode for increasing

the power transfer efficiency.

•

Low standby power with quiescent supply current < 1mA

4.5V operation enables low voltage supply

Proportional gate drive for fast turn-off

Operation up to 500kHz

Critical Conduction Mode (CrCM) & Continuous Mode (CCM)

Compliant with Eco-design directive

“Lead-Free”, RoHS Compliant (Note 1)

Halogen and Antimony free. “Green” Device (Note 2)

Qualified to AEC-Q101 Standards for High Reliability

The device is comprised of a differential amplifier detector stage and

high current driver. The detector monitors the reverse voltage of the

MOSFET such that if body diode conduction occurs a positive voltage

is applied to the MOSFET’s Gate pin. Once the positive voltage is

applied to the Gate the MOSFET switches on allowing reverse current

flow. The detectors’ output voltage is then proportional to the

MOSFET Drain-Source voltage and this is applied to the Gate via the

driver. This action provides a rapid MOSFET turn off as Drain current

decays to zero.
