LMR33630-Q1: Derivation process of output capacitance formula

Hi,

Actually there are different starting points for calculating the output capacitor, like voltage ripple, transient performance, loop response..You can find some explanations on the below note:

Hi Iven,

i can't find the answer from the document you provided. i know that there are different starting points for calculating the output capacitor, like voltage ripple, transient performance, loop response. Below is the start points of the formula, and it is easy to understand.But the formula on LMR33630-Q1 is hard to understand, i just want you explain how did we get this formula ?
