Abstract

A voltage supply arrangement for driving an electrical load, particularly a light-emitting diode, comprises a driver circuit (). The driver circuit () features a driver output () for making available a driver signal (SB) for controlling a load path () that comprises a means () for connecting the electrical load (). The driver circuit () furthermore comprises a device () for determining an AC signal component of the driver signal (SB), the input side of which is coupled to the driver output () and at the output side of which can be tapped a measurement signal (SI) that is dependent on the AC signal component of the driver signal (SB) and according to which a supply voltage (VOUT) of the load path () can be adjusted.
