The invention relates to a method for operating a load (12) connected to a motor vehicle electrical system (18) using a step-up converter (14). An input voltage (Ue) of the step-up converter (14) is ascertained, and a current (I) flowing from an output capacitor (42) and a valve (36) of the step-up converter (14) is ascertained. The valve (36) is opened or closed depending on the current (I) and depending on the input voltage (Ue). |
