• LT8641 VS. LT8643S

    HEY ALL,

    i'm designing a new board and considering using one of those parts: LT8641 / LT8643S

    wanted to know if someone can share from his experience regarding.

    as i know, the LT8643S is newer part, silent switcher 2 , which i cannot tell the difference…

    Hi, 

    I think you can implement this with an AND gate using a combination of FETs. Can you share your schematic?

    Regards.

  • a question regarding LT8643 output voltage ramp rate

    Hi

    Here is a question regarding LT8643 output voltage ramp rate, the schematic diagramwhich I used as below. The SS capatior I used is 0.1uF, Now I test the output voltage rising  time is 50ms which is so slow for me.I would like to get faster rising time…

  • RE: What replacement do you suggest for LT8640? I know that AD acquired LT. Thank you!

    Hello Roadrunner,

    the LT8643S is already a 2nd generation part of our silent switcher family, with its integrated caps inside to reduce the size of the hot loop even a better part than the LT8640. And it offers 1A more output current. But both parts…

    Hi 

    Base on our off line discussion and given the requirements 

    We would like to advice that you to use LT8640S/LT8643S which is designed for high voltage input with high output power

  • RE: Ripple Filter Damping Techniques

    Hi James, Kevin,

    Just to let you know I have tested the filter on a LT8643S supply (OK, it's not a part from Analog, but now LT is part of AD ). Fsw = 1.1MHz, Vout = 1V1, L1 = 1uH, C1 = 2uF, CD = 2uF, RD = 0R47, LFILT = 110nH, COUT = 300uF (all ceramic…
