UCC28019A: Question about UCC28019.

Part Number: UCC28019A

Hi

The customer's  waveform of MOSFET is as attached.

There is a section in which the gate is off and the MOSFET operates.

Certain samples perform this operation, and the EMI's conduction is also not good.

Can I know what the problem is?

-Condition-

1. Input : AC 220V

2. Output : 390V 0.8A

Thanks
