I am trying to drive 36 LEDs with a high frequency PWM signal using the evaluation board # LM3409HV . What I basically need is to drive these LEDs with a maximum current of 1.5 amp and modulate them on and off within the range of 10 μs. Will it be possible to connect three of the evaluation boards in parallel with the same PWM device in order to drive all 36 LEDs in phase with each other?
Another problem would be How can I limit the maximum current to 1.5A.? Thank you very much for your responses and I apologize If I am not stating my problem clearly.
