Abstract
Example embodiments provide a device that includes a power transformer with a first output voltage terminal providing a first voltage and a second output voltage terminal providing a second voltage, a voltage regulator coupled to one or more of the first output voltage terminal and the second output voltage terminal, and a power storage element that stores power supplied by the second output voltage, and the first output voltage terminal supplies power to a remote entity until a load power requirement of the remote entity exceeds a threshold power level at which time the power storage element is used to provide power from the second output voltage terminal to the remote entity.
