Abstract

Driver unit (11) for a voltage-controlled switching element (13), comprising- a first output terminal (29) for connecting a control terminal (20) of the switching element (13),- a second output terminal (30) for connecting a further terminal (21) of the switching element (13),- an output stage section (31) having a high-side terminal (35) and a low-side terminal (36) and being controllable to connect one of its terminals (35, 36) to the first output terminal (29) of the driver unit (11) based on a control signal (23) representative switching the switching element (13), and- a DC conversion section (32) configured to supply the output stage section (31) and to convert an input voltage (41) into a positive first voltage (45) between the high-side terminal (35) and the second output terminal (30) of the driver unit (11) and into a positive second voltage (46) between the second output terminal (30) of the driver unit (11) and the low-side terminal (36),characterized wherein the DC conversion section (32) is configured to provide the first voltage (45) and the second voltage (46) such that, when a value of the first voltage (45) is above a threshold value, a value of the second voltage (46) increases more than the first voltage (45) with an increase of the input voltage (41).
