Abstract

The current invention relates to a driver(10,20) for driving at least one main load and one auxiliary load comprising: ä power converter(101) adapted to convert an input voltage(Vin) into at least one main output voltage provided through a main output(1011) for driving said main load, and at least one auxiliary output DC voltage through an auxiliary output(1013) for supplying said auxiliary load, ä controller(103)adapted to control the main output based on at least one input set point, wherein the power converter(101)comprises a switched capacitor converter comprising a plurality of switches and a plurality of capacitors, the main output(1011)being connected to at least one internal node of the power converter (101), the auxiliary output(1013) being connected to a DC node of the power converter(101).
