    摘要: A voltage converter (10) comprises an input (11) for receiving an input voltage (VIN), a first output (12) for providing a first output voltage (VPOS) and a second output (13) for providing a second output voltage (VNEG). The first output voltage (VPOS) and the second output voltage (VNEG) have opposite polarities. A switching arrangement (14) of the voltage converter (10) is designed to provide energy to an inductor (15) in a charging phase (A) of operation and to provide energy from the inductor (15) to the first output (12) and, via a flying capacitor (16), to the second output (13) in a discharging phase of operation. The first duration (t1) of the charging phase (A) of operation is controlled such that the difference between a first predetermined value and the sum of the absolute value of the first output voltage (VPOS) and of the second output voltage (VNEG) is minimized.
