Hi! I have made a scheme for CREE X-ML2 LED (with maximum output at 3A) in eDesign studio. But missed that IC loses 0.8w power at 3A and getting very hot quickly, then stepdown output current to ~2A. Is there any way to fix it without total redesign(with different IC) or big additional heatsink on IC?
