Abstract
Power supply equipment includes circuitry for converting an input voltage to first and second DC output voltages. At least one of the output voltages is programmable in response to a voltage control signal. A first output port provides the first DC output voltage to a first electronic device and a second output port provides the second DC output voltage to a second electronic device. The conversion circuitry provides power sufficient to simultaneously power the first electronic device at the first DC voltage and the second electronic device at the second DC voltage.
