Hello Team,
My customer is currently using the UCC21225aEVM-365 board and has three of them and all of them do not have an operable low side driver but the high side driver is working perfectly fine.
They are applying 5V to VIN-GND and applying a 10kHz 50% duty cycle PWM at 3.3V from FPGA. The VDDA-VSSA is supplied and isolated from 5V (On all three EVM) with 12V and the VDDB-VSSB is 12V non-isolated to 5V.
They having trouble getting this to work. Any help would be greatly appreciated!
Regards,
Renan
