Abstract
Circuits for a voltage regulator are provided, comprising: an inductor having a first side coupled to an input voltage; a first flying capacitor; a second flying capacitor; and a plurality of switches, wherein: in a first state, the plurality of switches couple: a second side of the inductor to a second side of the first flying capacitor and an output node; a first side of the first flying capacitor to a first side of the second flying capacitor; and a second side of the second flying capacitor to a voltage supply, in a second state, the plurality of switches couple: the second side of the inductor to the first side of the second flying capacitor; the second side of the second flying capacitor to the output node and the first side of the first flying capacitor; and the second side of the first flying capacitor to the voltage supply.
