Abstract: A method, apparatus, and system are described in which operating characteristics of voltage regulator (VR) may be controlled. Example operating characteristics that are controlled may be 1) power conversion efficiency based on load demand on the VR, 2) response rate to a transient deviation from a regulated output parameter, such as voltage or current, of the VR based on either 1) measured load or 2) receipt of an indication from a first load communicating that anticipated load conditions may cause the transient deviation from a set point of the regulated output parameter due to a significant change in load demand, or other similar operating characteristic. The VR may select an operating input voltage from two or more input voltages to control the operating characteristics of the VR by receiving a selection signal. Other embodiments are described.

Abstract: In some embodiments, a system comprises a voltage regulator having two or more inputs with each having its own input voltage level and at least one switch to select between the input voltage levels, a configurable battery pack comprising at least two cells and at least one switch capable of configuring the battery in either a series configuration or a parallel configuration, a detector to measure a load parameter on the system; and a controller to send a signal to the at least one switch to select between the input voltage levels based on the measured load parameter.
