Abstract:
1. A switching converter having a plurality N of outputs providing N output signals, wherein N is an integer number N>1, and at least one inductor, comprising: a first controlling device for controlling the total energy flowing over the inductor to the N outputs dependent on a first control signal, wherein the first controlling device is a common mode controller and wherein the common mode controller is configured for adaptive control mode by switches that connect the output feedback voltages depending on an output signal of the common mode controller via inverse-phase controlled switches the respective inputs of the common-mode controller; at least a second controlling device for distributing the total energy between the N outputs by means of at least a second control signal, wherein the second controlling device is a differential mode controller receiving output feedback voltages; wherein the first controlling device is coupled to all N outputs for receiving a number M of the respective feedback output signals of the N outputs, M≦N, wherein the first controlling device comprises first means for weighting the M feedback output signals and second means for providing the first control signal dependent on the weighted M feedback output signals and wherein the first means are adapted to weight the M feedback output signals by means of at least one output current of a respective output signal.
