Abstract
A circuit arrangement () for driving light-emitting diodes comprises a number N of current regulators (), which each comprise a control input () and a load terminal () for providing a load current (IL, IL) to an electrical load () which can be coupled, in each case having a light-emitting diode ('). Furthermore, the circuit arrangement () comprises a compensation circuit (), which is coupled to the control inputs () of the number N of current regulators () and is designed to adjust the respective load current (IL, IL) in a load-dependent manner.
