1.1 Introduction

The UCC21551CQEVM evaluation module is designed for evaluating TI’s UCC2155XX family of gate drivers. The UCC2155XX is a 5.7-kVrms isolated dual-channel gate driver 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 guide provides a complete EVM schematic diagram, printed circuit board layout, bill of materials, test setup, and feature descriptions for the UCC21551C. To evaluate other Iso-Drivers in the UCC2155XX family, TI recommends that the user read the data sheet thoroughly before switching the part in the EVM covered by this user guide.
