I would like to purchase led drivers(LT3474) for my project(Visible light communication) which is capable of accepting a pwm signal from a microcontroller. I just have a few questions.
1) How many LEDs in an array can I drive with a single led driver?
2) Can it receive a modulated signal from a micro-controller and switch on and off the LEDs depending the signal. And if there is no modulated signal on the pwm pin, will the led driver continue to drive the LEDs at DC?
This is for my undergraduate project and it would be lovely if you can clear my queries at the earliest.
Thank you.
