I am testing below LED Driver Circuitry on breadboard using LM3410X.
Vin & DMM = 5V,
L = 20 uH
Only thing is I have'nt connected LED ( I am testing with 10k resistor as dummy load) But somehow I am getting 4.86 V at o/p ( across 10K load resistor )
Can anybody help me to figure out. Do I need to connect LED string?
Thanks in advance. :)
