Claim Text:
1. A combined power and input/output system, comprising: a host system operable to drive a high voltage and a low voltage on a combined power and I/O line; a target system operably coupled to the host system via the combined power and I/O line; and a power boost circuit in the target system coupled with the combined power and I/O line and operable to convert the high voltage supplied on the combined power and I/O line to a voltage higher than the high voltage, wherein the higher voltage is stored on a power supply capacitor, wherein the power boost circuit comprises an inductor and a diode interposed between the host system and the power supply capacitor on the combined power and I/O line; and a switching system operable in cooperation with the power boost circuit to charge and discharge the inductor into the power supply capacitor during communication when said combined power and I/O line is at the high voltage.
