Abstract
A voltage converter comprises a first, a second and a third capacitor (11, 12, 13) which are switched in series in at least one operating state, an input (1) for supplying an input voltage (VIN), an output (2) for providing an output voltage (VOUT), and a compensation circuit (5). The input (1) of the voltage converter is coupled to a capacitor from a group comprising the first, the second and the third capacitor (11, 12, 13). The output (2) of the voltage converter is coupled to a capacitor from the group comprising the first, the second and the third capacitor (11, 12, 13). The compensation circuit (5) is coupled to the first, the second and the third capacitor (11, 12, 13) and adapts a first voltage (V1) of the first capacitor (11), a second voltage (V2) of the second capacitor (12) and a third voltage (V3) of the third capacitor (13) to one another.
