I'm looking for circuits that regulation total power dissipation as an LED warms. That is, the current is adjusted to compensate for forward voltage drop changes with temperature such that E*I is maintained at a nominal level as determined by a voltage input. Also, there is to be 100% duty cycle at a chosen output level.\nI found such a circuit at http://www.maximintegrated.com/app-note ... vp/id/4470
