Claims34
An apparatus, comprising:
- a resonant switched capacitor arrangement having a first node and a second node, the resonant switched capacitor arrangement to include a first plurality of inductors to be coupled to the second node;
- and
- a regulator arrangement having a second plurality of inductors in an electrical configuration with the resonant switched capacitor arrangement;
- wherein the first node of the resonant switched capacitor arrangement to be coupled to a first voltage supply node, wherein the resonant switched capacitor arrangement is operable to provide, via the second node of the resonant switched capacitor arrangement, a first intermediate voltage based at least in part on a particular topology;
- wherein the regulator arrangement to receive the first intermediate voltage at the first node of the regulator arrangement and wherein the regulator arrangement to generate a regulated voltage at a second node of the regulator arrangement based, at least in part, on the electrical configuration and the particular topology.
