Abstract
A power supply arrangement () comprises a voltage regulator (), a driver circuit (), and a control circuit (). The voltage regulator () has a voltage regulator input () for the feeding of an input voltage (VIN), a voltage regulator output () to which an electrical load () is coupled that comprises a current source (), a feedback input (), and a comparator () that is coupled at a first input to the feedback input (). The driver circuit () has a driver output () that is connected to a control terminal of the current source (). The control circuit () comprises a control comparator () that is coupled at a first input with a signal output () of the driver circuit () and at an output with the feedback input () and also to which, at a second input, a reference signal (SR) can be fed.
