Calibrating buck LED driver by altering Vsens
Basically you are putting a pot in parallel with Rsns in order to "allow" two current settings. Why don't you use a fixed resistor and a 0.1" jumper. Normally the jumper would be in place for the higher current thru the LED then you remove the jumper to activate the lower current feed. I also don't like pots much and would much rather use a resistor and jumper especially if the two settings are known and fixed.
