3 Description

The UCC2720xA family of high-frequency N-channel

MOSFET drivers include a 120-V 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 1-ns

between the turn-on and turn-off of each other. The

UCC2720xA are based on the popular UCC27200/1

drivers, but offer some enhancements. 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 –18 V 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 UCC27200A are offered. The

UCC27200A has high-noise immune CMOS input

thresholds while the UCC27201A has TTL-compatible

thresholds.

Both devices are offered in an 8-pin SOIC (D),

PowerPad SOIC-8 (DDA), SON-8 (DRM) package, a

9-pin SON-9 (DRC) package and a 10-pin SON-10

(DPR) package.
