Abstract

A DCDC converter includes a controller, an up/down counter, a first power stage and a second power stage. The controller generates an up/down control signal. The up/down counter generates a first power stage control signal and a second power stage control signal based on the up/down control signal. The first power stage generates a first output current at a first phase and at a first voltage based on the first power stage control signal. The second power stage generates a second output current at a second phase based on the second power stage control signal. The up/down counter modifies the first power stage control signal to control the first power stage such that the first output current attenuates from a first power stage output to a secondary first power stage output. The controller can further output a control signal to modify the first voltage of the first power stage.
