Claim Text:
1. A DCDC converter comprising: a controller operable to generate an up/down control signal; an up/down counter operable to generate a first power stage control signal and a second power stage control signal based on the up/down control signal; a first power stage operable to generate a first output current at a first phase and at a first voltage based on the first power stage control signal; a second power stage operable to generate a second output current at a second phase based on the second power stage control signal; wherein said up/down counter is a digital counter operable to modify the first power stage control signal to control said first power stage such that the first output current changes stepwise in a plurality of steps controlled by the digital counter in one of increasing or decreasing output current; and said up/down counter is operable to modify the second power stage control signal to control said second power stage such that the output current changes stepwise by a same amount in another of increasing or decreasing output current.
