I am trying to understand compensation using TPS40200 https://www.ti.com/lit/ds/symlink/tps40200.pdf, the flow is given in Page 26 to 30 of the document.

This sentence is bit is irrelevant in Page 29, because Kfb feedback gain is already calculated previously as
HTML:
11.4dB
the only remaining factor is error amplifier gain how can we justify?

- And later amplifier gain including feedback is calculated using this

How is this derived from the compensation circuit ?
