• RE: LTM46XX series (R504 Family) susceptibility to Space Radiation

    Hi SYoung,

    Thanks for reverting.

    The specific part numbers are :

    1) LTM4650A

    2) LTM4644

    3) LTM4632

    4) LTM4620

    The local Field Applications Engineer I was assigned to previously is not familiar with these parts. Is there other avenue to address this ?

  • RE: LTM4653 LTpowerCAD support?

    thanks for the reply. I synced several times but the only LTM465x are the LTM4650A?(-1)?. I even reinstalled LTpowerCAD v2.5.5 without success. Will give it another try on monday.

  • RE: LTM4650A 5.5V supply


    The LTM4650A is available in LTSPICE library. By setting up the system according to the standard LTM4650A demo board DC2603-A, I have got the simulation working with 5.5V output voltage with 50A load. I will send this working simulation to your…

  • Max ambient temperature for LTM4650A


    We are trying to run a bank of LTM4650A regulators at the highest ambient temperature possible, ideally approaching 125C . The datasheet states that the maximum junction temperature for this device is 125C. Is there a rule of thumb, or better still…

  • LTM4650A: Syncing to external clock: Power-up and failure modes


    I've already asked a very similar question concerning the LTM4644 and like to know whether the answer also applies to the LTM4650A.

    I'd like to know whether there are any sequencing requirements for supplying an external clock to the LTM4650A…

  • RE: LTM4650 parallel operation for 300A

    Hello Joseph,

    Can you provide your email address and I will send you a LTPower CAD file for 300A operation.

    Is it for LTM4650 or LTM4650-1 or LTM4650A

    To generate a 300A template, blue box in the converter specification are required to be filled in.…

  • RE: 一图解析 ADI 电源产品的发展趋势

    LTM4650A 是一款双通道 25A 或单通道 50A 输出开关模式降压型 DC/DC μModule (微型模块) 稳压器,其具有 ±1% 的总 DC 输出误差。封装中内置了开关控制器、功率 FET、电感器和所有的支持组件。LTM4650A 可在一个 4.5V 至 16V 的输入电压范围内运作,支持两个输出电压范围为 0.6V 至 5.5V (各由单个外部电阻器来设定) 的输出。该器件的高效率设计能够为每个输出提供高达 25A 的连续电流。


  • RE: .file_attr 1="1";

    Hi Gideon,

    I moved this thread to the "CrossCore Embedded Studio and Add-ins" forum as it appears a tools related issue.

    I suspect that one of the automatic file attributes is being replaced by a macro define in the compiler generated assembly…

  • LTC6813-1

    Application Question for LTC6813 and similar parts.  Using the cell balancing capability of these devices is not required, is it?  If not, what do you do with the unused pins?

    Additionally, I plan to use the part to measure a string of 12V VRLA batteries;…

  • LTC3721-1 ΘJc


    I'm considering the LTC3721EGN-1,
    Is there data on ΘJc for this IC?

    Best regards,
