Tool/software:
Hi Experts,
This is Skylar responsible for GREE. GREE refers to our reference design PMP21529. GREE shorten Q4 and removed Q3 first to test UCC27211A's function. MCU is set as 80% and 20%.
Here are the HO and LO waveforms as below.
After suffering the abnormal output of HO for a while, the UCC27211A is damaged which causes the 12V VDD is shorten.
Could you pls help on this issue? Thanks!
BR,
Skylar
