ZXGD3107N8
Description
ZXGD3107N8 synchronous controller is designed for driving a
MOSFET as an ideal rectifier. This is to replace a diode for increasing
the power transfer efficiency.
Proportional Gate drive control 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 controllers’ output voltage is then proportional to the
MOSFET drain-source voltage and this is applied to the Gate via the
driver. This action minimizes body diode conduction while enabling a
rapid MOSFET turn-off as drain current decays to zero.
