(1) Load regulation in No Frequency or Pass-Through is given by IR drop across SWP switch resistance..
(2) Includes voltage drop when transitioning to No Frequency or Pass-Through Mode, where V_AUX is no longer a closed loop regulated
voltage and drops to V_NFM – I_LOADR_SWP. For No Frequency or Pass-Through, ΔV_AUX/ ΔV_IN = 1.
