The input-to-output transfer function of a buck converter is investigated including power transmission line parameters, accounting for printed circuit board (PCB) parasitics. A closed-form relation is developed for the transfer function to be used in small-signal analysis. Also, the effect of power transmission lines is demonstrated on control-to-output transfer function of the converter.
