ZXGD3101T8

Synchronous rectifier controller for flyback converters.

Zero Point Detector Driver ‘ZPDD’

Description

The ZXGD3101 is intended to drive MOSFETS Once the positive voltage is applied to the Gate

configured as ideal diode replacements. The the MOSFET switches on allowing reverse

device is comprised of a differential amplifier current flow. The detectors' output voltage is

detector stage and high current driver. The then proportional to the MOSFET Drain-Source

detector monitors the reverse voltage of the reverse voltage drop and this is applied to the

MOSFET such that if body diode conduction Gate via the driver. This action provides a rapid

occurs a positive voltage is applied to the turn off as current decays.

MOSFET's Gate pin.
