A voltage supply arrangement is proposed, which provides a voltage from a first power range in a first operating mode and from a second power range in a second operating mode, to a first electrical load. The voltage supply arrangement includes a voltage converter which is coupled on the input side to a voltage input of the voltage supply arrangement and on the output side to a first connection of a first switch, which is connected at a second connection to a voltage output of the voltage supply arrangement for connection of a first electrical load. The voltage supply arrangement further includes a second switch, which is coupled at a first connection to the voltage input and at a second connection to the voltage output, and a drive circuit, which is configured to set the first and the second switch to the first or the second operating mode in response to a control signal.
