Title of Invention

A POWER SUPPLY UNIT OPERATING WITH A BATTERY

Abstract The present invention discloses a power supply unit. The power supply unit operating as a DC-DC converter with a battery (B), the power supply comprising a switching transistor (T1), which is arranged with its current terminals (D,S) in the current path of the battery (B), characterized by comprising a protective circuit for the switching transistor (T1) arranged across the current terminals (D,S) of the switching transistor (T1) and having a threshold circuit for evaluating the differential voltage across the switching transistor (T1), and, in that the power supply unit or an appliance connected downstream in the event of too high a differential voltage across the current terminals (D,S) of the switching transistor (T1), is switched off.
