Abstract
In a circuit for supplying a load with a direct voltage, a diode is connected in a current path for supplying the load, a step-up converter is connected in the current paths parallel with the diode, and a control unit drives the step-up converter according to predetermined criteria in order to supply the load at least partially via the step-up converter. Such a circuit has advantageous power consumption characteristics. In comparison to conventional circuits that require an expensive filter, this circuit is more economical and/or has a smaller structural size.
