Abstract
The present invention relates to a device for limiting transient variations of a voltage for supplying a load from a dc/dc converter, including an input terminal, that receives the voltage provided by the converter, and connected to an output terminal of the device connected to the load; a first power transistor connected between a supply voltage of the converter and the output terminal; a second power transistor connected between the output terminal and the ground; and means for linearly and individually controlling each power transistor in case of an abrupt variation of the load.
