1 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.
2 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
UCC21520DW , UCC20520DW , UCC21521CDW and UCC21530DWK data sheets and TI's Isolated gate driver
