Abstract
A switching voltage regulator and a method of providing transition control therein. The regulator includes: (1) a modulation circuit for generating switching signals, (2) first and second switches coupled between a regulator output of the voltage regulator and respective first and second voltage inputs, control inputs of the switches coupled to the modulation circuit to allow the switches to couple the regulator output alternately between the voltage inputs as a function of a state of the switching signals and (3) a regulator output power waveform transition control circuit coupled to the control inputs of the switches for generating an override signal to the control inputs under a specified condition, the override signal causing the switches to couple the regulator output to the first voltage input independent of the state of the switching signals.
