A switching arrangement has a charge pump with a first contact connected to a first voltage potential, and a second contact connected via a circuit to a second voltage potential higher than the first voltage potential. The circuit has a first capacitor, a second capacitor and a first diode. The second contact is also connected to the first capacitor via a switching element. The charge pump has a third contact connected to an output of a first comparator having a first and a second comparator input. The first comparator input is connected to an anode potential of a second diode at which the second voltage potential is applied. The second diode is connected to the first diode and the second capacitor. The second comparator input is connected to a cathode potential of a third diode at the allocated anode of which the second voltage potential is applied.
