  • Hi,

    I have already answered this question on your other question.

    You can use the formula below in computing for the appropriate soft-start capacitor:

    Css=(tss*2uA /0.8V)  F

    where in:

    Css = capacitance required in Farads(F)

    tss = desired soft-start timing in seconds(s)

    2uA is the charging current for LTM8051 while 0.8V is its reference voltage for soft-start voltage.

    For this instance, you need to change the 2uA and 0.8V depending on the controller you are using.
