Abstract
A driver circuit for a light-emitting diode arrangement has a supply terminal for connecting a voltage source. A boost converter inductance connects the supply terminal to a common circuit node. A switching unit connects the circuit node to ground depending on a switching signal. A rectifying unit connects the circuit node to an anode terminal for the light-emitting diode arrangement by way of a circuit branch to which a terminal of a storage capacitance and a terminal of an RC element are connected. A cathode terminal for the cathode side of the light-emitting diode arrangement is electrically connected to the circuit node. A buck converter inductance is connected in each case between the rectifying unit and the anode terminal and/or between the cathode terminal and the circuit node.
