Abstract
The disclosure relates to a circuit arrangement that includes a first DC-DC converter that is connected on the output side to a capacitor. A first terminal of the capacitor is a supply voltage terminal and a second terminal of the capacitor is a reference potential terminal. The circuit arrangement also includes a second DC-DC converter, which is connected on the input side with the capacitor and on the output side to a first terminal of a piezo actuator. The second terminal of the piezo actuator is connected to the first terminal of the capacitor.
