• Problems with LTM4620A

    Hi,

    we have designed a supply system for a FPGA with the LTM4620A power module, for generating a output reference of 0.95V / 26A with the parallel mode (both outputs are tied together) from a 12V input source. The circuit is showed in the image below…

  • LTM4620A与LTM4620V怎样选择

    在12V转双路1.5V的应用中,选用LTM4620A好呢?还是选用LTM4620V呢?

    从LTM4620A与LTM4620V的功能、特性上看,LTM4620A似乎完全能够兼容LTM4620V,那么为什么还要推出LTM4620V呢?

    我很困惑,希望了解情况的能够为我解惑。谢谢。

  • LTM4620A input supply current when it use single 26A output?

    LTM4620A : 5V ==> 4V@26A 

    I want to know about input supply current of LTM4620A for singe 26A ouput.

    In datasheet, input supply current is 

    S(VIN) Input Supply Current VIN = 5V, VOUT = 1.5V, IOUT = 13A ==> 4.6A (typ)

                                                 VIN = 12V…

  • RE: LTM4620A minimum Vin

    Hello,

    The minimum of 4.5V Vin is valid when using INTVcc. The use of EXTVcc is mainly for improving the efficiency. Please do not exceed 6V on INTVcc and EXTVcc pins. In addition, please keep in mind that the maximum duty cycle for this device is 95…

  • LTM4620A Output Voltage Change Question

    hi team

    A circuit diagram was designed using LTspice, as shown in the attached picture.
    When the voltage on the TK/SS pin changes, so does the output voltage.
    Can you explain what the problem is?
    The circuit diagram did not observe the reference,
    Is there…

  • LTM4620A temperature measurement not being used.

    Is it possible to connect J6 (TEMP) to GND or leave it floating? Should be ok, if it is just connected to a (PNP) diode internally, but all of the examples use a resistor to Vin to set an appropriate current, despite the temperature measurement never…

  • NEED HELP FOR LTM4620A (5V/25A)

    Hi, 

     We are using above circuit for 5V/25A.

    Above circuit is it working ? or any changes require?

    can you give me feedback

  • LTM4620 POWER GOOD abnormal behavior!

    Hello I am so glad that now also linear is part of Analog Devices and I can ask my question in this good community.

    In our custom board we used LTM4620A for 3.8V and 2.3V output. both output voltages are good without any problem. Power Good of channel…

  • LTM4676A output voltage setting

    Hello Analog experts,

    I used LTM4620A in my last design but now I want to use LTM4676A because it has wider input voltage range. Output voltage of LTM4676A can be set either with PMBUS or by PIN Strapping. I want to use PIN Strapping for setting the…

  • RE: LTM4620AEV help needed urgently

    Hello Theresa,

    It is recommended to arrange the two close output voltage channels at one LTM4620A module.

    The frequency setting does not directly affect the output voltage regulation. But care needs to make to ensure

    1) Frequency selection ensure  Ton…
