Abstract
Embodiments of the invention are directed to a device that includes a battery having an output of a battery voltage, a step-up voltage converter, a high voltage circuit, a low voltage circuit and a controller. The step-up voltage converter includes an input that is coupled to the battery voltage. The step-up voltage converter is configured to produce a high supply voltage at an output. The high voltage circuit is coupled to the output of the step-up voltage converter. The controller selectively powers the low voltage circuit using either the output from the step-up voltage converter or the battery voltage.
