All i can find is state space ones.
Im trying to find something that is in the S domain and clearly outlines how the answer was derived.

It's the response of the analog control feedback loop in a linearized model where the switching frequency is not directly included.But can someone explain to me how an equation in the frequency domain applies to a buck converter, which operates at a single frequency?
if this is true, im not sure how people go about getting the answer. I have seen what the S domain transfer function is. Its listed in several reference books. But i have no clue how they got it. I would like to see the derivation.You may have trouble finding one -- the s-domain is a Laplace Transform from a space in which the system is described by a set of linear, time-invariant differential equations. My understanding is that if you transform other types of differential equations, you simply end up with a set of non-linear differential equations in the s-domain.
So what is normally done is to linearize the original set of differential equations, which is exactly what the purpose of small-signal analysis is.
See Equation 15 in SLUP340.if this is true, im not sure how people go about getting the answer. I have seen what the S domain transfer function is. Its listed in several reference books. But i have no clue how they got it. I would like to see the derivation.
And you won't get a clue if you don't look at the references we posted.But i have no clue how they got it. I would like to see the derivation.
