  • ADM1272 ENABLE issue

    Hi ADI

    We have use ADM1272 for 54V hotswap, but there has a problem that it can't be re-start when ENABLE is triggered.
    Here’s the condition below while occurring fault, could you help to analyze what happened?
    Test method: like warm boot at system…

  • ADM1272 I_Set

    Hi , I have some problems for ADM1272 Eva-Board. I calculated resistance values for I_SET. These resistance values are 100Kohm (Vcap to Iset) and 226Kohm (Iset to GND)  I want I_SET = 1.9 volt. Therefore , It will be V_SENSE= 20mV and Current limit = 20…

  • 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…

  • 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 Estart&Efault Pin

    Hi ,

    I have a ADM1272 Eva Board. It is not clearly information related Estart and Efault pins. The subject has been opened before. But nothing has been explained. Which formulas are applied here? Thanks for your help.
