3 Description
The UCC2720x family of high-frequency N-channel
MOSFET drivers include a 120V bootstrap diode
and high-side and low-side drivers with independent
inputs for maximum control flexibility. This allows
for N-channel MOSFET control in half-bridge, fullbridge,
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 turnon and turnoff of each other.
An on-chip bootstrap diode eliminates the external
discrete diodes. Undervoltage 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 UCC2720x are offered. The
UCC27200 has high noise immune CMOS input
thresholds while the UCC27201 has TTL compatible
thresholds.
