Abstract
A two-stage multi-phase switching power converter operates its first stage during nominal operation responsive to a nominal clocking frequency and operates its second stage during the nominal operation responsive to a second-stage clocking frequency that is greater than the nominal clocking frequency. In response to an application of a load, the first stage temporarily increases its clocking frequency from the nominal clocking frequency and implements a fixed duty cycle.
