Classification: CPC H | IPC H

Claim 0:
1. A system comprising:
a power converter configured to generate a first supply voltage at a first supply output of the power supply, the power converter having a maximum allowable input power drawn from a power source;
an energy storage element coupled to an output of the power converter at a top plate of the energy storage element, wherein the energy storage element is configured to store excess energy; and
a second supply output configured to generate a second supply voltage lower than the first supply voltage, wherein:
the second supply voltage tracks an envelope of an output signal generated by an amplifier coupled to the power supply when the amplifier consumes power from the second supply output; and
the second supply voltage regulates a voltage at a bottom plate of the energy storage element when the amplifier consumes power from the first supply output.
