TPS92513HV: figure 5 characterization data needed

Part Number: TPS92513HV

hi,

I'm looking for the spread data of the curve in figure 5 of the TPS92513HV datasheet.

do we have upper and lower limits (at least for the factors related to the IC)?

thanks a lot in advance

    Hi Vincenzo,

    Please refer to the electrical characteristic table -- Analog current adjust (VIADJ, VISENSE).
    That shows you the spread on the ISENSE pin voltage with different VIADJ input.

    Thanks!

    hi Isaas,

    thanks for the prompt reply...

    yep, that was also my 1st though, as

    ILED = Visense / Risense
    and
    Visense = Vadj / 6

    I know the spread of Vadj and Risense but not of the "6", i.e. the missing part is the spread of the Vadj/6 (that's the typ. only).

    it is enough an high level indication like for example <X% or something like that...

    thanks a lot in advance

    Hi Vincenzo,

    "6" is typ, but the min max values has included the variation of this "6" in.
    For instance, VIADJ = 0.18V, you get typ at 30 mV at VISENSE.
    However, we guarantee it will be 21.4 mV min and 40 mV max (including the variation of the "6").

    Thanks!
