Description

This reference design demonstrates the combination of a UCC21732 gate driver with a UCC14xxx series bias supply. This board can be used to drive a variety of power switches, including connecting directly to a Wolfspeed SiC FET module. This board can serve as either a high- or low-side driver, or it can be tested with a capacitive dummy load.
