Abstract
A DC-DC converter for converting an input voltage at an input node, the converter comprising: first and second inductor nodes for connection of an inductor therebetween; first and second flying capacitor nodes for connection of a flying capacitor therebetween; a first switching network for selectively connecting the first flying capacitor node to each of the input node and the first inductor node; a second switching network for selectively connecting the second flying capacitor node to each of the input node and a reference voltage node; and reservoir circuitry, comprising: first and second reservoir capacitor nodes for connection of a reservoir capacitor therebetween; a third switching network for selectively connecting the first reservoir capacitor node to each of the first and second flying capacitor nodes; a fourth switching network for selectively connecting the second reservoir capacitor node to each of the second flying capacitor node and the reference voltage node.
