Claim:
1. An LED driver circuit permitting dynamic operation range control for powering an LED array, the LED driver comprising: a power converter configured to generate an output voltage and an output current for driving the LED array; a dimming interface circuit configured to generate a dimming control signal based on an input received across first and second dimming input terminals; a tuning interface circuit configured to removably couple to the first and second dimming input terminals and to provide a programming signal associated with at least one of the output voltage and the output current; a controller configured to regulate the output voltage and the output current generated by the power converter, based on the dimming control signal, a sensed output from the power converter, and at least one of a programmed maximum output voltage and a maximum output current value associated with the power converter, the dimming interface circuit, and the tuning interface circuit; and a tuning interface sensing circuit, the tuning interface sensing circuit comprising
