Abstract:
A control system for regulating an output voltage of a DC-DC converter having N phases, where N is an integer greater than one, includes a pulse generator and a frequency divider. The pulse generator generates a stream of fixed on-time pulses, each pulse triggered in response to current through an alternating one of the N phases falling to a threshold value. The frequency divider divides the stream of fixed on-time pulses into N phase signals for controlling the N phases. A method for regulating an output voltage of a DC-DC converter having N phases, includes the following steps: (1) generating a stream of fixed on-time pulses, each pulse triggered in response to current through an alternating one of the N phases falling to a threshold value, and (2) dividing the stream of fixed on-time pulses into N phase signals for controlling the N phases.
