Abstract: A circuit arrangement includes a first number of loads connected in series. Each of a second number of drive units is coupled to at least one of the first number of loads, and is configured to assume a first operation state or a second operation state. A current source circuit is coupled in series with the first number of loads and is configured to control a load current.
