Title: Circuit arrangement for a timed power supply

Abstract: The invention relates to a circuit arrangement for a timed power supply having an integrated circuit connected to first and second supply potential terminals and includes a switching mechanism, a control circuit that controls the switching mechanism, and a first diode. A coil is additionally provided, which is connected to the switching mechanism and to a first output terminal. A load is connected between the first output terminal and a second output terminal and a first charge storage unit is connected in parallel with the load. The switching mechanism includes a first and a second semiconductor switch. This makes possible a timed power supply that features a low power loss and a low electromagnetic radiation.
