circuit analysis
Ultimately the AC ripple current through the resistor tends towards zero and the ripple current in the capacitor remains at a constant. Capacitor ripple current remains constant because it is defined by the inductor and input voltage to the regulator and, to make this analysis clearer it makes sense to consider the input voltage to be constant.
