Mobile voltage supply circuit operating method in which the circuit can be operated in energy saving mode, especially for a motor vehicle safety system, whereby in energy saving mode two point regulation is used

摘要

Method for operating a voltage supply circuit in energy saving mode, whereby, instead of the normal voltage supply operating mode, a two point regulation with respect to the output voltage (UH) at the output (A21) of a first voltage converter (2) is undertaken using a voltage converter switch and a length regulator (3).
