Tool/software:
Hi,
I am facing a issue in my power supply section, the UCC28702 flyback IC is failing during EFT(bust) test.
The IC is failing during 4KV, P-N at 5KHz level. The IC is flikering for 4 to 5 times and totaly going dead.
Remaining all voltage levels like 500V, 1KV and 2 KV it is passing.
The test is conducted as per IEC 61000-4-4.
Need your help on this issue.
