Abstract
The disclosed embodiments provide a system that operates a power supply. During operation, the system disposes a first switching mechanism between a first output of a first power converter and two or more loads. Next, the system obtains two or more error signals for the two or more loads, wherein each error signal from the two or more error signals represents a difference between a load voltage of a load from the two or more loads and a first reference voltage for the load from a first set of reference voltages for driving the two or more loads using the first power converter. The system then uses the first switching mechanism to couple the load with a largest error signal from the two or more error signals to the first output.
