Hi all
I have been trying to run 2 - 3 1watt ir leds in series at there peak forward current (1000mA) from a arduino at 5us high and 100us low which is a high frequency, I have tried different mosfets and some transistors but I am not getting the current I need.
Could some one please recommend the best circuit for this or a led driver ic ?
