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.
