Abstract
Various embodiments of charge adjustment techniques for a switched capacitor power converter are described. In one example embodiment, briefly, charge adjustment techniques may include a technique to control operation of a charge pump for a switched capacitor power converter so that the charge pump is able to adjust the charge of a selected one or more of the two or more charge pump capacitors along a charge transfer path, independent of the charge of other charge pump capacitors of the two or more charge pump capacitors. Likewise, in some instances, a charge may be adjusted in a manner that is to include at least one of the following: a current source, a voltage regulator, an adjustment of switching frequency of a charge pump, a time-based charge operation, a bypass switch with respect to at least one charge pump capacitor, on-resistance modulation for one or more switches of the charge pump, or any combination thereof.
