Zusammenfassung:	A personal computer includes a DC to DC converter which employs a dual function capacitive energy storage device at the output rail of the converter. The energy storage device provides both a transition control function and a bulk or output function. In this manner, the size and expense of a separate bulk capacitor is advantageously avoided. The converter includes a switching transistor coupled to a bulk inductor. The switching transistor exhibits a high frequency switching rate which is sufficiently high to permit the inductor to directly replenish the capacitive energy storage device thus enabling the converter to withstand both major and minor load fluctuations without loss of voltage regulation at the output rail.
