ABSTRACT:
A method includes a voltage converter outputting an output voltage that is based on an input voltage and on a first multiplication factor, determining a predicted current sink voltage based on a new multiplication factor obtained from a set of selectable values, based on a signal derived from the input voltage, based on a load voltage across an electrical load, and based on a correction voltage. The method also includes comparing a predicted current sink voltage with a predetermined threshold value and outputting the new multiplication factor to a control input of the voltage converter if the predicted current sink voltage exceeds the predetermined threshold value.
