LT3443 with multiple LEDs

Question

Hi 
 Can I use the LT3743 to drive two LEDs with different VF (first LED 3V, seodn LED 2x3V= 6V) ? The LT3744 can do this. Can I do the same with LT3743? 
 Thank you

Hi Nizan, 
 I don't see any reasons why you can't. The LT3743 regulates the output current so the current going through 2 LEDs is the same. Make sure to set the maximum output voltage greater than the total forward voltage of 2 LEDs.)
