Patent ID: 8729829

Claim:
A power supply arrangement for the driving of an electrical load, in particular, a light-emitting diode, comprising a driver circuit-comprising: a driver output configured to provide a driver signal to a current source of a load circuit that is configured to be coupled, the load circuit comprising the current source and a means for connecting the electrical load; a signal output configured to provide a measurement signal that is configured to be determined by a measurement of a current value of the driver signal and is provided for the setting of an output voltage, wherein the output voltage is configured to be fed to the load circuit that is configured to be coupled; a first complementary transistor pair with a first transistor and a second transistor, wherein a node between a controlled section of the first transistor and a controlled section of the second transistor is coupled with the signal output of the driver circuit; and a second complementary transistor pair with a third transistor and a fourth transistor, wherein a node between a controlled section of the third transistor and a controlled section of the fourth transistor is coupled with the driver output.
