Abstract
A voltage regulator coupled to an unregulated DC input voltage source by an input terminal, and to a load by an output terminal is disclosed. The voltage regulator converts an input voltage at the input terminal to an output voltage at the output terminal. The voltage regulator includes a master controller and one or more slaves, and each slave includes a switching circuit which serves as a power switch for alternately coupling and decoupling the input terminal to an intermediate terminal, and an internal controller which sends a same control signal to each slave. Each internal controller includes a phase-locked loop which offsets the control signal so that each slave is phase-offset relative to the other slaves.
