Abstract
A switching regulator configured to generate an output voltage from an input voltage, includes an inductor, an output capacitor configured to generate the output voltage based on a current passing through the inductor, a flying capacitor, and a plurality of switches. The plurality of switches are configured to operate in at least one of a buck-boost mode or a boost mode to, charge the flying capacitor to the input voltage in a first phase, and provide a boosted voltage from the flying capacitor to the inductor in a second phase, the boosted voltage being generated by charge pumping from the input voltage.
