UCC27200A, UCC27201A
SLUSAF9B – FEBRUARY 2011 – REVISED JULY 2015
UCC2720xA 120-V Boot, 3-A Peak, High-Frequency, High-Side and Low-Side Driver
1 Features
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.
