Beschreibung
Zusammenfassung:	A driver for driving a load, wherein the driver comprises a dual-boost converter comprising an output capacitance comprising a first output capacitor connected in series with a second output capacitor, a first switch connected to a power input stage via a first inductor and arranged for controlling charging of said first output capacitor via a first diode and a second switch, connected in series with said first switch, and connected to the power input stage via a second inductor and arranged for controlling charging of said second output capacitor via a second diode; wherein a centre tap of said in series connected first and second output capacitor is connected to a centre tap of said in series connected first and second switch.
