"Webloop gain is the product of the modulator voltage gain and the current-sense gain, which is also in volts/amp. The modulator voltage gain is reduced by the equivalent divider ratio of the load resistor RO and the current-loop gain Km · Ri. This sets the dc value of the control-to-output gain. Neglecting the dc loss of the sense resistor: O m i ... " - Flyback loop
