• ADM1270 ==> IC Burned (Burned after power on)

    When entering 19V, ADM1270 occurs in the following three conditions.

    ADM1270 => IC Burned (Burned after power on)

    ADM1270 => IC Hot (Ic started hot)

    ADM1270 => (Vcc=19V, Vcap no output.)

    Is there a problem with the design?

  • About ADM1270 ADISimPower Tool

    Dear All:

    I recently tested ADM1270 EVB Board encountered a great deal of trouble? because ADM1270 had a lot of external resistor. capacitors to control ADM1270,Every time to waste a lot of time to calculate it. ADI have supply ADM1270 ADISimPower excel…

  • RE: ADM1270 Surge Stopper Function


    The ADM1270 has a overvoltage (OV) comparator that monitors for an input exceeding the resistor programmable threshold.

    Once the power rail crosses the OV threshold the ADM1270 immediately turns off Q1 by driving the Vgate high.

    In this figure…

    You may be interested in something like the ADM1270?


    Or implement something with comparators and latches.

  • ADM1270 Issue

    hi sir

    I  want to design the ADM1270 in my system, but I have two issue need to clarity before layout

    Q1.ADM1270 use the PMOS to be the switch, but PMOS cost Which expensive than NMOS, Why ADI use PMOS?

    Q2.ADM1270 Have reverse protect by RPFG,But I…

  • RE: I need IBIS model for ADM1270


       Regarding ADM1270, we do not have IBIS models. The ADM1270 does not have a digital bus, so there are no SI concerns.

        If you have specific questions about hook-up or routing, please send me your schematic and I will be happy to review it.

    Unfortunately we do not have a simulation model of the ADM1270 at this time.

    Hi Sreejith,

    The ADM1270 and similar current limiter products don't have UL approval.
