Why does the calculation of ESR ripple in Formula 13 include the Iout(max)/(1-D) term? This seems to be the DC component

Hi Cao,
Please refer to the following app note and post:

Hi Cao,
The output cap is a bulk cap which sources voltage and current when the FET switches on/ off depending on the topology. During these transient events, the ESR will add ripple.
