    LT3957A – Chip Power Dissipation.pdf

    Hi Attila,

    I have prepared a short PDF file and I agree with Peter about the approximate chip power loss.

    Kindly see the file and tell us what you think.

    Thanks!

    Hi dtluigi, 

    Isw is defined on page 12 as the internal switch current, which is the current flowing through the internal MOSFET M1 inside the IC.

    Vpeak is supposed to be Vsw(peak). It was a typo. 

    Now, let me break down the formula for you.

    Isw^2*D*Rds…

  • LT3957AIUHE#PBF v LT3957AEUHE#PBF Difference

    Hi,

    What is the difference between theLT3957AIUHE#PBF  and the LT3957AEUHE#PBF parts please?

    They both seem to have the same temperature rating but they are a different price.

    Thanks

    Andrew
