ZXGD3101T8
Synchronous rectifier controller for flyback converters.
Description
The ZXGD3101 is intended to drive MOSFETS
configured as ideal diode replacements. 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.
Features
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
reverse voltage drop and this is applied to the
Gate via the driver. This action provides a rapid
turn off as current decays.
