A DC-DC converter (1) transforms DC voltage, referred to as 'power supply voltage' (Ui), into a comparatively higher output voltage (Uo). A controller (2) affects the DC-DC converter in accordance with the output voltage, which it regulates. The DC-DC converter acts as an up-converter having a reservoir choke (L1), a switch (S1) operating as a NMOS transistor, a diode (D1) and a filter capacitor (C1).
