The UCC27201A is a high frequency N-Channel MOSFET driver that includes a bootstrap diode and
high-side/low-side driver with independent inputs for maximum control flexibility. This allows for N-Channel
MOSFET control in half-bridge, full-bridge, two-switch forward and active clamp forward converters. The low-side
and the high-side gate drivers are independently controlled and matched to 1-ns between the turn-on and turn-off
of each other. The UCC27201A is based on the popular UCC27201 drivers, but offers some enhancements. In
order to improve performance in noisy power supply environments the UCC27201A has an enhanced ESD input …
