Apparatus for Improving the Effective Performance of a Power Source and Associated Methods

Abstract:

An apparatus includes a power management circuit to receive an input voltage and to generate and provide a first output voltage to an energy storage device. The power management circuit further generates and provides a second output voltage to a load. The first output voltage is greater than the input voltage, and the second output voltage is smaller than the first output voltage. The apparatus further includes a monitor circuit to monitor the first output voltage and to provide a signal to the load to indicate when the load may perform an operation.
