Abstract

A step-up converter converts a battery voltage to an intermediate voltage. The intermediate voltage is greater than or equal to the battery voltage. A step-down converter receives the intermediate voltage supplied by the step-up converter and controls an output voltage which is less than or equal to the intermediate voltage. The step-up converter controls the intermediate voltage in an open loop depending on the battery voltage, at least if the battery voltage is lower than a first predetermined value, and at least if at the same time the load on the output of the step-up converter exceeds a minimum load.
