Power stage providing higher magnitude current in a switching converter

A switching converter comprising:

• a power stage operable to drive a current through an inductance in a duration specified by a periodic control signal;
• and
• a phase controller to generate said control signal to cause said power stage to generate a regulated supply voltage,
• wherein said power stage is designed to communicate with said phase controller on a path,
• wherein said power stage comprises a first sub-stage and a second sub-stage, wherein each of said first sub-stage and said second sub-stage respectively drives a first sub-current and a second sub-current via corresponding inductors in response to said control signal, wherein said corresponding inductors together provide said inductance,
• wherein said path is used for communication between said first sub-stage and said phase controller, and then between said second sub-stage and said phase controller in alternate cycles of said control signal,
• wherein said path is used to communicate a magnitude of current provided by said power stage,
• wherein each of said first sub-stage and said second sub-stage is designed to indicate on said path twice a magnitude of each of said first sub-current and said second sub-current respectively in corresponding alternate cycles of said control signal.
