Abstract

A load control circuit includes one or more current regulators, in particular in an electronic motor vehicle control unit, wherein one or more preferably inductive load(s) is/are connected to a circuit located outside the control unit or inside the control unit, and wherein the load current flowing through the load(s) is or can be reduced by way of one or more step-down converters to a voltage potential below the supply voltage. A step-down converter includes a clocked DC/DC converter having at least one clocked switch and an energy storage medium, in particular a capacitor, for conversion, wherein the clock control of the switch or switches is modified according to the charge state of the energy storage medium and wherein the charge state is determined according to the voltage present at the energy storage medium.
