SLUUBG8B – June 2016 – Revised November 2018
Using the UCC21520EVM-286, UCC20520EVM-286,
UCC21521CEVM-286, and UCC21530EVM-286
UCC2x5xxEVM-286 evaluation modules are designed for evaluation of TI's 5.7-kV
RMS
isolated dual-
channel gate driver family with 4-A source and 6-A sink peak current for driving Si MOSFETs, IGBTs and
WBG devices such as SiC and GaN transistors. This user's guide covers the UCC21520EVM-286,
UCC20520EVM-286,
UCC21521CEVM-286,
and
UCC21530EVM-286
used
to
evaluate
the
UCC21520DW, UCC20520DW, UCC21521CDW, and UCC21530DWK, respectively. To evaluate other
Iso-Drivers in the UCC2x5xx family, TI recommends that the user read the data sheet thoroughly before
switching the part in the EVMs covered by this user guide. In this user guide, the UCC21520EVM-286
evaluation module is shown as the primary example, and the key differences between the
UCC21520EVM-286 and the UCC20520EVM-286, UCC21521CEVM-286, and UCC21530EVM-286 will be
highlighted accordingly.

Introduction
Developed for high voltage applications where isolation and reliability is required, the UCC2x5xx delivers
reinforced isolation of 5.7 kV
RMS
and a surge immunity tested up to 12.8 kV along with a common-mode
transient immunity (CMTI) greater than 100 V/ns. It has the industry’s fastest propagation delay of 19 ns
and the tightest channel-to-channel delay matching of less than 5 ns to enable high-switching frequency,
high-power density, and efficiency.
The flexible, universal capability of the UCC2x5xx with up to 18-V VCCI and 25-V VDDA/VDDB allows the
device to be used as a low-side, high-side, high-side/low-side, or half-bridge drivers with dual PWM input
or single PWM input. With its integrated components, advanced protection features (UVLO, dead time and
enable/disable), and optimized switching performances, the UCC2x5xx enables designers to build smaller,
more robust designs for enterprise, telecom, automotive, and industrial applications with a faster time to
market.

Description
The UCC2x5xx evaluation board has three independent screw terminal blocks for VCCI, VDDA, and
VDDB. The 3-position headers with jumpers for all the key input signals, such as PWM INPUTs (INA, INB
or PWM), dead time (DT) programming and enable/disable function (EN/DIS), allow designers to easily
evaluate different protection functions. A variety of testing points also support most of the key feature
probing of the UCC2x5xx. Moreover, the PCB layout is not only optimized with minimized loop area in
each gate driver loop and power supply loop with bypassing capacitors, but the layout also supports high
voltage test between the primary side and secondary side with 120-mil PCB board cutout. Importantly, the
creepage distance between two output channels are maximized with bootstrap diode in footprint of
TO252-2(DPAK), which facilitates high-voltage, half-bridge testing for a wide variety of power converter
topologies. For detail device information, refer to
