1. An apparatus comprising:
a first power converter operative to: i) produce a first output current derived from an input voltage, and ii) convert the input voltage into an intermediate voltage;
a second power converter operative to produce a second output current based on the intermediate voltage received from the first power converter;
an output node operative to output a summation of the first output current and the second output current to produce an output voltage; and
wherein the first power converter is operative to output the intermediate voltage to the second power converter from a capacitor switched in and out of a circuit path of the first power converter.
