A serial bus network includes a voltage regulator, a plurality of power switches, and a voltage monitor. The voltage regulator provides power to a plurality of serial buses. Each of the serial buses provides power from the voltage regulator to a device coupled to the serial bus. Each of the power switches switches power from the voltage regulator to one of the serial buses, and includes an input terminal coupled to a voltage regulator output, and an output terminal coupled to one of the serial buses. The voltage monitor is coupled to the voltage regulator and to the output terminal of each of the power switches. The voltage monitor compares bus voltages at the output terminals of the power switches, identifies a lowest of the bus voltages, and adjusts the voltage regulator output voltage such that the identified lowest of the bus voltages is within a predetermined operational voltage range.
