Abstract
The invention relates to a buffer circuit for a load (LAS) to be supplied by the supply DC voltage (U ), comprising a buffer capacitor (Cp), which may be charged to a voltage (U ) by means of a charging circuit (HSS). Said voltage is higher than the supply voltage and may be brought in for supply of the load by means of a step-down controller (TSS). An input of a step-down controller (TSS) is connected to the buffer capacitor (C ) and the output thereof to the load (LAS), whereby a trigger circuit (TRI) is provided to activate the step-down controller on drop-out of the voltage (U ) at the load.
