I've used the TLC5940's dot correction with low power LEDs with success before. Would it be possible to use the TLC5940 to drive an N-FET with a high power LED >1000ma and reap the benefits of the built in dot correction? I have an LED array of four LEDs and need to produce a region of very uniform high intensity light. Is there an alternative product that would be more appropriate? The high power LED drivers I've found do not have dot correction.
