Hello Expert,
Our customer is considering to use 1KHz FMOD DITHER function for EMI issue.
Then, they'd like to understand pros/cons of this.
As far as I confirmed, biggest cons is output voltage variation.
Also, I found following documents for triangular modulation which is adopted in TPS55288-Q1.

Then, is there any specific material or explanation for the pros / cons at DITHER function in TPS55288-Q1 or buck-boost converter?
Best regards,
Kazuki Kuramochi
