Abstract
A DC/DC converter is provided for operation within a narrow voltage range during normal conditions, while allowing for a wider input voltage range for short periods of time. A first switch is coupled across first and second input terminals, and a capacitor is coupled in parallel with the first switch and across the input terminals. A second switch is coupled in series with the first input terminal and between the first switch and the capacitor. Operation of the switches is regulated in accordance with a bypass mode of operation when received input power is within a defined range, and a boost mode of operation when received input power is less than a threshold value, wherein the received input power is boosted to a bulk output power within the defined range. Boost operations may in various embodiments be provided via, for example, a critical conduction scheme or continuous conduction scheme.
