Other Parts Discussed in Thread: UCC28780,
Dear support member,
I used UCC28780.
I have a question about switching waveform.
(Specification condition)
Vin:250Vac
Vout:12Vdc
Iout:2A
(Situation)
The switching waveform was measured by UCC28780 EVM-002.
The switching waveform is stepped.
(Question)
What causes the stairs to occur?
Could you teach reason?
I attached the waveform.
Could you check it?

Best regard.
