Title: why a compensator is not required for PFM mode buck converter
Post by electronics_rama on Apr 21^st, 2016, 1:21am

Hello,

Consider a DC-DC buck in PWM mode. Let us assume that this converter goes to DCM mode. In this scenario also, we use compensator in the loop.

But, in case of PFM mode, we do not use any compensator. What is the explanation for this?

I'm not understanding this concept. :-/

Thanks,
Rama
