Do you agree that equation 35 of page 10 of AN-4137 is incorrect?
AN-4137:
https://www.fairchildsemi.com/application-notes/AN/AN-4137.pdf

It surely should say…

VFB/Vo1 = - (wi/s) . [ (1+s/wzc) / (1+s/wpc) ]

Do you agree?

This is confirmed by equation 3-58 of page 290 of Basso’s book “switch mode power supplies” (attached)
