Abstract

See full text

A DC-DC converter includes a first capacitor which can be charged by a power-supply voltage; a second capacitor that generates the output voltage using electric charge previously discharged by the first capacitor; a comparator that compares the output voltage with a reference voltage and outputs a comparison signal that shows whether the output voltage is below the reference voltage; multiple switches that switch to allow the first capacitor either to be charged or to discharge its charge to the second capacitor, and a controller that controls the switch timing of the multiple switches on the basis of the comparison signal.
