Abstract
A power supply circuit comprises an input for receiving a power supply from a battery and a DC/DC converter for supplying a converted voltage to a load. A regulator is used for controlling the DC/DC converter such that the current drawn from the converter is smoothed. A charge storage device at the output of the DC/DC converter enables delivery of a non-constant current to the load.
