An information handling system ("IHS") includes a system board and a power supply unit coupled to the system board. The power supply unit includes a switching power regulator. The switching power regulator includes an inductor coupled to an output, a capacitor coupled to the inductor, a switch, coupled to the inductor, for regulating power supplied by the power supply unit in response to a duty cycle, and a control circuit, coupled to the switch, for supplying current to the inductor while the switch is closed and charging the capacitor while the switch is open.
