Hi,
We are trying to calculate the open loop small signal feedback loop transfer function for an LT3680 based buck converter.
As you know, this is given by the [Power stage transfer function] x [Error amp transfer function] x [Modulator transfer function].
The Equation 2A-5 in the attached gives the [power stage & modulator transfer function]. However, it contains the term “R/Ri”.
How can we find out what Ri is for the LT3680?
(Ri is the FET source sense resistor; R is the load)
