Abstract
A device may be associated with a power source. The device may include a charge pump configured to output a pulse-width modulated voltage based upon an input voltage from the power source, with the pulse-width modulated voltage varying between a first voltage and a second voltage. The device may also include a low-pass filter comprising an output capacitor, with the output capacitor being configured to average the pulsed-width modulated voltage and to output a filtered voltage having a value different than that of the input voltage. The device may further include a controller configured to selectively decouple the charge pump from the power source when a load imposed on the low-pass filter is below a threshold load.
