    Dear all,

    I want a design a low cost 12 W LED driver in CC mode with output dim-able is not needed.
    To do i have selected part number of power integration LNK403 for universal input range 85-300VAC.

    I will be using 1W LEDs that is 12 LEDs in series.
    If LEDs Vf=1.4V

    So my questions is-

    1. What will the output voltage we can fix.
    2. How much current needed to give full brightness.
    3. How can it be said , this is CC LED driver and how we define a constant current.
    4. What would be the voltage to give maximum constant current.
    5. What is no load and full load output voltage.

    Could anybody elaborate all these.

    Thanks in Advance !!!
