Abstract

A system for providing power to a wireless card includes power interface that provides power to a compact flash card. A boost regulator boosts the power from the power interface. A battery provides power that is summed with the power from the power interface. Moreover, a buck regulator limits the voltage of the summed power. A compact flash card can be powered by the power interface while a wireless card can be powered by the summed power.
