Abstract
A voltage converter () comprises an input () for receiving an input voltage (VIN), a first output () for providing a first output voltage (VPOS) and a second output () for providing a second output voltage (VNEG). The first output voltage (VPOS) and the second output voltage (VNEG) have opposite polarities. A switching arrangement () of the voltage converter () is designed to provide energy to an inductor () in a charging phase (A) of operation and to provide energy from the inductor () to the first output () and, via a flying capacitor (), to the second output () in a discharging phase of operation. The first duration (t) 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.
