• RE: LT8650S

    Hi Travis,

    Apology but I believe we don't have this available other than θJA in datasheet. Can you share why these are important and not able to use θJA? I would recommend that you connect to local ADI FAE if you insist on getting those requested…

    they only differ in test coverage. Please have a look on Note 2 on page 4 for details



  • LT8650S and FPGA

    Hello all.

    I've an old board with XC6SLX9 FPGA that needs 1.2V and 3.3V voltages; I must update the old board changing only the power and I'd like to use the LT8650S. 

    Is LT8650S suggested to power FPGA like XILINX SPARTAN6?

    Thank you.


  • LT8650S - Generating 0.85V


    I am looking forward using LT8650S to generate 0.85 et 0.9V.
    Is this part suitable for these 2 low voltage for an FPGA?


  • Problem with LT8650S

    LT8650S.pdfI realized a board with LT8650S. The schematic is here attached.

    My idea is to have two different OUTPUTs VH and VL_I from the LT8650S. The max current for VH will be 1.5A and the max current for VL_I will be 0.5A

    In this circuit, I can change…

  • LT8650S Switching frequency


    When using the datasheet formula to calculate RT we get a different result from LTPowerCAD Model.

    Wich one should be used?


  • LT8650S - Spice Model - Enabling


    It is indicated in the datasheet that both channel can be enabled/disabled separately. But on LTspice, I noticed that when the channel-1 is disabled, channel-2 is also disabled even though it's enable pin is driven high. Probably this is an issue…

  • LT8650 Minimum Inductor Calculation

    I am looking for guidance on calculating the minimum inductance required to prevent subharmonic oscillation on the LT8650.  I found the mention of APP NOTE 19 (which is an amazing reference) and the details there.  I was not able to locate the Sx Voltage…

  • LT8650S LTSpice sequenced startup


    I am currently trying to simulate some sequenced startup following the datasheet under LTSpice.
    When doing so, none of the output start. There seems to be an issue with the LTSpice model.
    Could you help?


  • LT8650S 2 phase LTPowerCAD model


    I am looking forward using the LT8650S in 2 phase to generate 0.85V 5A.

    Can you provide an LTPowerCAD model in this configuration? I need to check for external compensation.
