Hi Ian,

what would be the application conditions and the purpose of these bode plots?
What is their main concern?

Hi,

My customer's end-customer has a hardware check list with some general design philosophy/requirement.

The bode plot is one of these items and it is to prove that the buck convertor is stable enough. (by checking the phase state when gain is 0dB.)

There will be no concern if the phase is not 180degree when gain is 0dB. Pls help for it.

Thanks, Ian.
