Part Number: UCC256303

Hi TI Team, I have observed noise on VCR pin.

VCR - sinusoidal voltage suddenly dips by 1 V at the +ve peak. why?

Also I would like to know the ways to eliminate the noise in VCR waveform.

Hello,

Could you send me waveforms of this behavior?

Does it occur on the EVM?

Is there any special test condition that makes this behavior occur?

Does it cause and output regulation issue?
