I was going through the application note "SLVA477B–December 2011–Revised August 2015". the below equation is used to calculate the output capacitor. Let me know, where the constant 8 came in this equation. section 7 (Output Capacitor Selection).

We are going to forward your question to the right person. Somehow it is directed to us, the boost group.

This is a standard equation for any buck. Here is a more detailed analysis of the buck: www.ti.com/.../slva057.pdf

And here is 1 college presentation which derives the 8 (on slide 26): users.ece.utexas.edu/.../_6_EE462L_DC_DC_Buck_PPT.ppt Note that the Iout name listed there is misleading and is really Iripple/2.
