• RE: About ADM1270 ADISimPower Tool

    Dear AD,

    Further to this discussion:

    I used your "ADM1270 Design Spreadsheet tool", but it is limited for practical design, because I cannot change the R-values and see the resulting voltages.

    Currently voltage settings can be selected and…

  • ADM1270 VCAP and LDO active before EN?

    Hello,

    when EN low is at ADM1270, is the internal LDO and thus VCAP active?

    I ca not find any info from functional block digram and the text in the datasheet.

    Thanks for any help.

  • I need IBIS model for ADM1270

    Hello,

    I need IBIS Model for the following part numbers, in order to perform SI Analysis

    1. ADM1270ARQZ

    2. ADR440BRZ-REEL7

    3. ADG721BRMZ-REEL

  • 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?

  • ADM1270 stability during Current limit Switch over

    Hi,

    We are planning to design a 28V fixed power supply with adjustable current limit setting using ISET pin of ADM1270 IC in discrete steps,need to know information on how stable the device will perform,during change over from one discrete current limit…

  • 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…

  • ADM1270. Is there are any restrictions to use this controller in N 1 power redundancy?

    ADM1270. Is there are any restrictions to use this controller in N+1 power redundancy?

    In datasheet I found no details about pull-up pull-down mechanics in gate control of Q1 & Q2.

    Only found such parts:
