What you will learn
The Bode plot of a switching DC/DC converter
The phase margin of buck converter
A step load response of the converter
Phase margin, gain margin, and stability margin
Why take this course?
In this lecture, the concepts of frequency domain analysis, Bode plots, gain margin, phase margin, cross over frequency and the power supply stability criteria are explained.
Power supplies are mostly designed in the frequency domain to obtain a lot more information about the relative stability of the power supplies. In the time domain where the power supply is given a step load and looked at its transient response, the stability criteria are not investigated properly.

I would like to understand on how to write transfer function for Buck converter but its not derived in this video. Simply RC (LPF) transfer function explained and moved directly to Buck transfer function.
Please give explanation on Buck transfer function derivation.
