Abstract
Novel circuitry and methodology for operating a multiple channel switching regulator system to extend an input to output voltage ratio by setting individual constant switching frequencies to switching regulator channels. In the switching regulator system having at least first and second switching regulators, a first clock circuit supplies a first clock signal at a first clock frequency to define a switching frequency of one of the first and second switching regulators. A second clock circuit is synchronized to the first clock signal for producing a second clock signal at a second clock frequency different from the first clock frequency, to define a switching frequency of the other of the first and second switching regulators.
