The UCC2720xA family of high-frequency
N-channel MOSFET drivers include a 120V 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 1ns between the turn-on and turn-off of each
other. In order to improve performance in noisy power supply environments the
UCC2720xA has an enhanced ESD input structure and also has the ability to withstand
a maximum of –18V on its HS pin.
An on-chip bootstrap diode eliminates
the external discrete diodes. Under-voltage lockout is provided for both the
high-side and the low-side drivers forcing the outputs low if the drive voltage is
below the specified threshold.
Two versions of the UCC2720xA are
offered. The UCC27200A has high-noise immune CMOS input thresholds while the
UCC27201A has TTL-compatible thresholds.
