SYSTEM AND METHOD FOR SINGLE PHASE TRANSITION FOR MULTIPHASE DCDC CONVERTERS

摘要

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 an 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

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 operable to modify the first power stage control signal to control said first power stage such that the first output current attenuates from a first power stage output to a secondary first power stage output, wherein said controller is further operable to output a control signal to modify the first voltage of said first power stage.
