1. A circuit arrangement, comprising:
an input connection for supplying a supply voltage (Vin);
a load impedance;
a controlled current source which is coupled between the input connection of the circuit arrangement and the load impedance; and
a control means which has an output coupled to a control input of the controlled current source, wherein the control means is configured to output a control signal to the control input of the controlled current source based upon feedback received from a node located between the controlled current source and the load impedance, and wherein the controlled current source outputs a current which corresponds to the average current drawn by the load impedance based on the control signal.
