• RE: ADM1272 Estart&Efault Pin

    Hi Yusuf,

        The easiest way to think about the EFAULT and ESTART pins of the ADM1272 is as translating FET stress into voltage, which is then used to determine when to shut down. These pins output a current that approximates the FET stress (proportional…

  • RE: ADM1272 I_Set

    Hi,

        We have not yet released a design tool for general use. If you have a local ADI FAE please contact them for specific factory support. For your case please check the sense resistor value. Is it 2mOHM? Also, I assume that your input power supply is…

  • RE: ADM1272 ENABLE issue

    Hi Chester,

        If I understand correctly, and without seeing your schematic, I think that you may be having an interaction between discharge at the output and the PWRGD input threshold. If the output is not allowed to decay below the PWRGD threshold before…

  • ADM1272

    I would like to understand the method used to set the RC Network for EFAULT & ESTART Pins of ADM1272 . It's not clear to me from the datasheet .   I really appreciate any help , Thanks in advance

  • ADM1272 pins values

    Hi ,

    ADM1272 datasheet isnis clearly to understand. For example, I did not understand E_fault and E_start pins. Is there any design tool this hot swap ?

    Thanks a lot.

  • ADM1272 + (1) PSMN4R8-100BSE

    Hello,

    I'm looking at the ADM1272 and a single PSMN4R8-100BSE (as used in the ADM1272 EVAL board) for a couple of +48V based projects, and I have a couple of questions.  The first project is a cellular modem which for reception reasons needs to be…

  • ADM1272 Reading Vout Value

    Hi All,

     I am using ADM1272's evaluation board(EVAL-ADM1272EBZ). I am trying to code PMBus interface via VHDL. I want to read the Vout value for a specific application but I can't. According to datasheet, there are some procedures for reading Vout. I followed…

  • ADM1272 custom MOSFET & Rsense footprint

    Dear Sir,

    My customer is designing new project using ADM1272, might I request for ADM1272 EVM's footprint & dissension as below ?

    Thank you!

  • Does the ADM1272 require a minimum output capacitor?

    Dear Sir,

    My customer is now testing their own ADM1272 board. Some ADM1272s are not designed with output capacitors. Testing is a bit problematic now. The test with output capacitance is normal. As shown in the first picture. The test without output capacitance…

  • What different between Istart and Inrush current for ADM1272?

    Hi ADI Expert,

    I am confused about this.  What different between Istart and Inrush current for ADM1272?

    Thanks.
