interesting.. but it's only 1 LED on that IC, do you know if there's something similar but that drives many separate LEDs independently?
Well one driver can drive several leds if they are wired in series and the drive has an output voltage higher then the combined voltage drop of all the series leds wired in series. However if you want to control each led independently then each would require it's own constant current driver.
