Abstract
A programmable driver for driving a solid state lighting device includes a processing circuit, a voltage feedback loop and a power stage. The processing circuit is configured to determine a voltage reference signal based on a nominal current setting and a predetermined power limit. The voltage feedback loop is configured to receive the voltage reference signal and to determine a difference between a reference voltage indicated by the voltage reference signal and a drive voltage of the solid state lighting device. The power stage is configured to limit maximum output voltage for driving the solid state lighting device based at least in part on the determined difference between the reference voltage and the drive voltage of the solid state lighting device provided by the voltage feedback loop.
