Abstract
An automatically reconfigurable Buck-Boost DC-DC converter having an input supply and an output voltage includes a linear regulator (LDO) for Buck configuration; a switched-capacitor DC-DC converter; a capacitor and switch array, and a gain selector to switch between the linear regulator (LDO) when an output DC level is higher than an input DC level (Buck configuration) and the switched-capacitor DC-DC converter when the output DC level is lower than the input DC level (Boost configuration).
