Efficiency variation of UCC28180

Other Parts Discussed in Thread: UCC28180, UCC28019

I have a question about UCC28180.

Our customers are concerned about frequency variation(pulse-skip) at  light load.

Our customers used UCC28019 and referred the attached document to reduce influence of frequency variation(pulse-skip).

Our customer said that they could reduce the influence of frequency variation(pulse-skip) .

Question.

If we want to reduce the influence of frequency variation(pulse-skip) of UCC28180,

can we do the same method of attached document about UCC28019?

Best Regards,
