Can anyone help me out with designing a driver circuit to drive 3 Cree Xlamps at variable current from 3.3-3.7 volts and 90 mA (combined current) - 3000 mA (combined current), driving the three LED's at full power, this circuit would idealy use a hall effect sensor much like a U2 in order to controll the amount of current and voltage going to the LEDs, I was hoping their is a way to get a full 1024 step minimum 90-3000 mA range, using a Hall effect sensor with a neodymium magnet rotating in a 60 degree arc. I realized recently I should contact my cousin who is an EE in the making throuhg college.
