3 Description

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, twoswitch

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.
