• RE: About LT8641 output pulsed current value

    Hello gramalex,

    first you have to unveil the timing of your loaed cycle:

    10% of a second might be ok, 10% of a minute might be too much.It depends on how long the app needs to reach thermal steady state and the deltaT coming from the full load.

    Beside…

  • LT8641 FB problem

    Hello,
    We are currently in the production phase of an optical transceiver system which uses the LT8641 to supply 3.3V.
    The circuit of the LT8641 has been thoroughly tested and I was quite happy with its performance. Now that we are in the production phase…
  • 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…

  • LT8641 : Output Capacitor and Inductor recommended capacity value

    Hi ADI,

    We are testing the demo board of the LT8641.
    I have a few questions during the test.
    1. Recommended output capacitor value
     > There is no calculation formula in the Datasheet.
    2. It is recommended to apply De-cap 1uF to VIN1 and VIN2, but 0.1uF…

  • LT8641 operation above 5V output

    I am planning to use an LT8641 in a device powered over Ethernet (POE PD).

    One regulator will provide 3.3VDC for microcontroller, etc.  This models fine in LTSpice XVII, based upon the macromodel test fixture.

    A second regulator is intended to regulate…

  • RE: Paralleling of LT3065

    Hi 

    Based on the suggested schematic on the data sheet you would need to introduce an offset on the output of the second LDO however this would mean the abs max value of the out pin (40V)would be excided.

    Please try considering switching power supplies…

  • RE: LT8640IUDC#PBF won't output +0.9V

    I had a quick look at LT8641 and it has 0.81V feedback reference voltage. The pins are compatible too. Please check this in simulation first then test on your board.

  • RE: LT8640S - LTspice simulation of synchronous clocking - example jig does not seem to support this modelling

    i also tested the jig for LT8641 with external clocking. This time making sure the extern sync frequency is higher than the RT defined frequency as stated in the datasheet - also simulated for 10ms. There is no sign of synchronization taking place there…

  • RE: LTPowerCAD crash when opening file

    I was unable to reproduce the error. Including changing windows region and language settings for France those default solutions mentioned seemed to load without error. Can you send an image of the error message shown when you try to open the default solution…
