Abstract
Various embodiments of the invention provide for a multi-input switch regulator that is controlled to selectively receive power from one of multiple power sources in order to extend the range of available battery voltages at which the regulator can operate. Certain embodiments accomplish this by using an internal adaptive control circuit to coordinate multiple high-side switches to operate with a low-side switch to generate a desired output voltage.
