I am designing a LED driver for 20 LEDs of 3.5 V, using LinkSwitch-PH family. What happens if I wire less than 20 LEDs in the circuit? Will it work?
I will need the circuit to work with 4 to 20 LEDs, is this possible? I could not find information regarding this in the datasheet.
How can I know the variation margin allowable for the output voltage?
