Claim:
1. A combined power and input/output system, comprising: a host system comprising a switch configured to switch current from a source to a host line; a target system operably coupled to the host system via the host line, wherein the host line provides power and data; a power boost circuit in the target system configured to generate a supply voltage from a signal received on the host line, wherein the host system is configured to drive the host line to charge a power supply capacitor of the target system in a first mode; and wherein the host system is further configured to alternately connect and disconnect the power boost circuit with the source via said switch to charge and discharge the power supply capacitor when driving the host line during a communication in a second mode, wherein the power supply capacitor is charged to a voltage higher than a voltage provided by the host system.
