• RE: LT8640 Vs LT8640S Vs LT8640S-2

    Hi Ron,

    Thanks for the answer. Just wanted to know the difference in EMI-EMC performance of LT8640 and LT8640S-2? Which is better? Is LT8640S-2 is Silent switcher or silent switcher-2?

    Can I replace LT8640 with LT8640S-2 ? what will be the difference…

  • LT8640 Data sheet question

    On the first page of the LT8640 data sheet(s) there is a table describing all of the part variants. The far column is labeled INTERNAL CAPS. What are the internal caps? Thanks for any help.

  • LT8640 Thermal Resistance Values

    The datasheet for LT8640/LT8640-1 lists theta_JC(PAD) = 12 C/W.

    First, I would like to confirm that this represents the junction-to-board thermal resistance. Typically, JC denotes junction-to-case, however, in this case it calls out the PAD which makes…

  • LT8640S Average output voltage tolerance

    Hi team,

    I would like to estimate the tolerance of average output voltage.

    I think that only the feedback resistance tolerance and the reference voltage tolerance are relevant, but are there any other parameters that affect it?

    Since the ripple voltage…

  • RE: LT8640S LTpowerCAD simulation support date

    Please type into "Part #" column.  I can see that both LT8640 and LT8640S are already there.

  • LT8640S

    I have a design with two LT8640S devices.  They are set to generate 12V from a 24V input.  One is used to power devices on another board.  The other powers on-board devices.  The LT8640S for the off-board devices works fine and generates 12V.  The LT8640S…

  • LT8640S and LT1764A Reliability

    Hi all,

    I'm doing reliability analysis (according to Telcordia SR332 Issue 3 method).

    Fit/MTBF values given by Analog here follow another standard and are not comparable to Telcordia values.

    I need MTBF/FIT value (according to Telcordia) for this…
