Abstract: The present invention provides a voltage converter circuit for the clocked supplying of energy to an energy storage, based on an input voltage present at an input of the voltage converter circuit. The voltage converter circuit comprises an energy storage and a switch assembly, the switch assembly comprising a first switch and a second switch connected in parallel and coupled to the energy storage. The first switch of the switch assembly exhibits, according to magnitude, a smaller turn-on voltage than the second switch, wherein a control terminal of the first switch is switched such that the first switch is active in a starting phase of the voltage converter circuit in order to supply the energy storage with energy, and wherein a control terminal of the second switch is switched such that the second switch is active after the starting phase in order to supply the energy storage with energy in a clocked manner.
