A multi-phase converter comprising a plurality of switching circuits each
controlled by a phase controller and each providing a switched output
voltage to an output node of the converter and wherein each switching
circuit under control of the phase controller sequentially provides a
switched output voltage to the output node at which an output voltage of
the converter is developed; and a main control circuit including a clock
circuit for providing a first clock signal to each of the switching
circuits and a second lower frequency clock signal to a first of the
phase controllers, each phase controller having a delay circuit
controlled by the first clock signal to provide a delayed second clock
signal for coupling to a next one of the phase controllers and in the
case of a last one of the phase controllers, back to the main control
circuit, whereby a plurality of sequentially delayed second clock signals
is provided, one to each of the remaining phase controllers after the
first phase controller to determine when each switching circuit provides
the switched output voltage to the output node.
