• LTM4678 - VOUT and VTRIM configurations


    I'm currently working on the project that LTM4678 will be used for buck conversion from 12V to 0.95V and 1.8V.

    Here is the design scenario that I'm planning. 

    • LTM4678 12Vin >>> 1.8Vout 100A. The Vout0 and Vout1 are tied together. …
  • LTM4678 - Switching and Phase shifting configurations.


    In my application, I'm using 4 of LTM4678 for 4 individual buck convertor. They have the same output voltage 0.95V at 100A. (V0P95A, V0P95B, V0P95C.V0P95D) 

     My concern is about phase interleaving of these outputs since I'm using 18kohm strap…

  • RE: the problem of ltm4678 power module

    Calculating the compensation circuit parameters is not a trivial thing. The best way is still to use LTpowerCAD. LTpowerCAD gives recommended component values based on your design parameters. But finally whether the compensation works or not still has…

  • RE: LTM4678 programming sockets

    Hi Fil,

    We've same question regarding LTM4678 programming socket as well. Could you please provide "NP276-40009-A3931" data for us ? Also the sockets support gang programming ?

  • LTM4678 EVAL board (DC2552) OV Behavior

    I have a board design using two LTM4678 devices. 

    I am working with the DC2552A dev board for the LTM4678 device.  It is preset for 1.8 and 1.0 outputs.  I have the DC1613A attached.  Both operate as expected with no-load.  The 1.8V supply functions from no…
