Dimming Performance: Output Current vs. Analog Dimming
The FL77944 analog dimming function can be implemented with a few external components.
The converter output current at the rated line voltage can be adjusted within the range of 8.2% to 100% of
the nominal current value through 0 to 10 V A-DIM signal.
