LED LIGHTING DRIVER AND DRIVE METHOD

A driver is for driving a lighting load. A switch mode power converter is controlled in dependence on the input voltage, in particular so that the same current is delivered by a preset (fixed) switching mode at a first nominal operating voltage (Vr/2) and by a feedback (dynamic) switching mode at a...

Zusammenfassung:	A driver is for driving a lighting load. A switch mode power converter is controlled in dependence on the input voltage, in particular so that the same current is delivered by a preset (fixed) switching mode at a first nominal operating voltage (Vr/2) and by a feedback (dynamic) switching mode at a second nominal operating voltage (Vr). The first operating voltage corresponds to the voltage present when two drivers are connected in series across a power input, and the second operating voltage corresponds to the voltage present when a single driver is connected.
