The UCC2720x family of high-frequency N-channel MOSFET drivers include a 120-V 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, 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 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 UCC27200 are offered. The UCC27200 has high noise immune CMOS input
thresholds while the UCC27201 has TTL compatible thresholds.
