Abstract
An inverting switching regulator is provided. The inverting switching regulator is used to generate a negative output voltage based on a positive input voltage. The inverting switching regulator includes an inductor configured to pass an inductor current from a first terminal to a second terminal; a flying capacitor coupled to the second terminal of the inductor; and a plurality of switches configured to apply a negative voltage to the second terminal of the inductor by charging the flying capacitor by the positive input voltage during a first phase, and by connecting the flying capacitor in series to a ground node and the inductor during a second phase.
