I plan to run the led at 2.5v only and 200mA.
I have a tested the LED already, it's fine at 2.5V it takes 200mA and it's bright enough
Is there any way to drive a 3V led sinking 200mA from a 3V power supply using a microntroller which can at best source 40mA?
Apparently the only way is using a buck converter to ste-up the voltage and then use a CC driver?Thanks.
Any example that I can use as a startup point, on that web page all is pure theory.
