• externally forcing latch-off of ADM1275-2

    Can I use an external pullup to force the TIMER pin high (to VCAP) and thus cause a latching turn-off of the ADM1275-2? I'd like to do this to implement an overvoltage protection on a secondary voltage that is derived from its output. Please comment if…

  • ADM1275 foldback pin connection when not used?


    I have am designing ADM1275 into an application in which the foldback feature will not be needed. Can I the FLB pin to VCAP pin? That *seems* like the simplest way to handle this, I was hoping the datasheet would mention some recommendation. Please…

  • Any ADM1275 known Issue for Gate pin?

    Hi ADI Expert,

    My customer would like to ask is there any bug fixed for ADM1275 part regarding the gate functionality?

    Since there show the revision on ADM1275 datasheet which seems related to gate pin.

    Can you help to check whether this parts has…

  • Can I get a Spice simulation model for adm1270? (or a model for Simetrix, like for ADM1275)

    I'm using ADM1275 in my designs and I have simulated some of them in Simetrix. Now I need a high voltage version and I'm looking at ADM1270. The controlled voltage is in the range 4-60V, so I'd like to simulate some scenarios first. Is there any chance…

    Original Question: ADIsimPE schematic from UG-241 by rpmarchand


    i recently downloaded the ADIsimPE files as recommended in UG-241 and it seems to be missing a file for the ADM1275/ADM1276.  The MOSFETs PSM1R0-30YLC models are not included.  I checked…

  • Hot-swap sulution with PMBus and integrated temperature sensor


    My name is Meir and I am DFAE at Phoenix technologies in Israel.

    MRV, one of my castomers, is interested in hot-swap sulution with PMBus and integrated temperature sensor.

    I suggested them following ADI solutions: ADM1275. ADM1276, ADM1175,…

  • RE: ADM1276

    Hi There,

    The ADM1276 senses the current through the differential voltage across the sense pins (sense voltage).

    by default it will try to turn on the current regulation through controlling the gate of the external FET once the sense voltage reaches…

  • RE: ADI  Hot-Swap Current Shunt Resistors Select


    you can use multiple resistors in parallel to achieve the low value needed.

    The new ADM1278 will allow you to use a smaller voltage drop on the sense resistor due to it's accuracy.
