ABSTRACT:
A clamp device for a switching transistor of a D.C. to D.C. converter is non-conductive when the converter is ON. When the converter is turned OFF, the clamp device is placed in a standby state that clamps off the switching transistor and draws no power from the battery. When noise occurs the clamp device momentarily enables the converter, but only while such noise is present.
