• LTM4678 tray

    Hi

    I am looking for the drawing of LTM4678's tray.

    Which is correct drawing 50-8083 or 50-8078?

    If the other is correct, could you please send it?

    Best regards

    Hello,

    Where can I find details on bulk programming of the LTM4678 internal EEPROM?

  • which LTM4678 schematic symbol is correct?

    Downloading the schematic symbol from:

    I get an OrCad symbol that does not match the DC2552A demo board schematic, and appears to have the following mistakes:

  • 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…

  • LTM4678 wrong or incorrectly-ranging current readings

    When I program my LTM4678 outputs to +2.0V, I get a sensible small current from my open-circuit load.  When I then program it to >= +2.1V, suddenly it says it is drawing > 2.5A, which can't be correct for a small linear step and no load.  Changing…

  • LTM4678 must INTVCC have exactly 2.2uF bypass or are larger values ok

    Greetings,

    For part re-use I would like to bypass INTVCC with the same 4.7uF ceramic cap as EXTVCC, but the datasheet calls out 2.2uF.  Is this exact value needed to e.g. run an ADC, or is anything in the range of 2.2uF OK?   Thanks!

  • 三个LTM4678电源模块并联使用,上电初始电压1.0v,上电完成之后要求通过PMBUS改成0.85v,在修改过程中,3个模块之间电压不一样,会不会出问题?

    需求:12v输入,初始电压1.0v,上电之后通过PMBUS改为0.85v,电流150A;

    当前设计:

    1、三个LTM4678电源模块并联实现,上电初始电压1.0v,上电完成之后要求通过PMBUS接口改成0.85v,但是在修改过程中,3个模块电压不可能同时修改成0.85v,肯定有先后顺序。如果第一个模块电压改为0.85v,但是余下两个模块的电压还没有改过来,这个是否有影响?是否有参考设计?

    2、如果第一种方案不行,是否可以用1个ltm4678+2个LTM4650,这样是否可以使用?有没有参考设计?
