Abstract
An apparatus for converting a first voltage into a second voltage includes a reconfigurable switched capacitor power converter having a selectable conversion gain. converter includes a cascade multiplier switched capacitor network having capacitors, each of which electrically connects to a stack node and to a phase node. A controller causes the network to transition between first and second operation modes. In the first mode, at least one capacitor is isolated from a charge transfer path of the reconfigurable switched capacitor power converter. Consequently, in the first mode of operation, the power converter operates with a first gain. In the second mode, the power converter operates with a second conversion gain. Meanwhile, a third voltage across the at least one capacitor is free to assume any value.
