• ADuM3470: thermal derating

    I have some doubts about “thermal derating curve” of iCoupler products on the
    datasheet, these two curves confused me, could you please explain to me the
    meaning of these two curves?

     

    The thermal derating curve is developed like this…
  • ADuM3470 with VDD1>VDDA

    Can these Isolated supplies be used with 3V3 to the non-isolated supply input
    pin VDDA with the Isolated supply Primary at 5V supplying its common pin VDD1.
     The secondary (Isolated) output supply could be 3V3 or 5V or even 12V in our
  • Question for your ADuM3470

    Dear Sir/Madam,

    I have a question for you.

    As for your ADuM3470,

    Your datasheet Fig-39 show the recommend external capacitor Cin=10uF.

    But UG-197 show the recommened external capacitor C13=47uF.

    Which is more better you think? Or how should we select…

  • ADuM3470 efficiency over temperature range

    Have you any information concerning efficiency and power consumption changes
    with temperature - -40C to +85C?

    Are the efficiency figures for 5V in 5V out applicable to my application with
    the Primary digital side supplied by 3v3.
  • ADUM3470 in sync mode

    Hello ,
    Is it possible to synchronize frequency of internal oscillator if I will add 1MHz signal  to OC pin from external occillator ?

  • ADuM3470 Maximum Output Supply Current

    Hi,

    About How much current can the ADuM3470 supply with 3V input and 5V output ,4Mbps data rate?  

    Can I use such a configuration? I guess that it can supply only less than about 165mA,  250mA x 3V/5V.
    250mA is Iiso(MAX) specification with 3V input and 3V…

  • 视频分享:icoupler®数字隔离器——ADUM347x

    ADI出品的iCouplerRegistered数字隔离器ADuM347x是业界首款在单封装中集成变压器驱动器和PWM(脉冲宽度调制)控制器的数字隔离器。

    ADuM3470/ADuM3471/ADuM3472/ADuM3473/ADuM3474均为四通道数字隔离器,集成PWM控制器和变压器驱动器以驱动隔离式DC/DC转换器。该DC/DC转换器基于iCouplerRegistered技术,提供2 W、3.3 V至24 V的调节隔离电源,输入电源电压为5.0 V或3.3 V。这样在2 W隔离设计中,无需使用单独的隔离式DC/DC转换器。
