UCC21231AEVM-108 Evaluation Module
Description
The UCC21231AEVM-108 is a two copper layer
PCB containing multiple test points and jumpers to
fully evaluate the functionality of the UCC21231A
gate driver. The EVM features PWM input control,
bootstrapped high side power supply, options to use
bench top power supply, configurable dead time
options, and EN and DIS pin jumpers. The layout has
been optimized to minimize gate loop area for each
channel and placement of bypass capacitors allow for
clean and sharp signal reading with minimal noise
interference.
