Abstract
The operating voltage of an integrated circuit (e.g., a processor) is changed in response to one or more conditions (e.g., a laptop computer is connected to an AC power source). Both the operating frequency and the operating voltage of the integrated circuit are changed. The voltage regulator providing the operating voltage to the integrated circuit is caused to transition between voltage levels using one or more intermediate steps. The integrated circuit continues to operate in the normal manner both at the new voltage and throughout the voltage transition.
