  • 寻一款类似ADuM3070隔离应用的芯片，但是需要+12V或+24V输入

    尊敬的ADI技术专家和各位工程师朋友，我购买了一块ADuM3070的测试板，我看到它是+5V输入，可以由单芯片完成隔离电源的全部设计，我们需要这样的结构，但我们的电源是+12V或+24V，我尝试将变压器的+5V输入截断，接入+12V或+24V，但芯片仍然是+5V输入，然而不能工作。因此，想寻找一种可以在+12V或+24V工作的，类似ADuM3070工作方式的电源芯片，请指导，输出需要5V，100mA即可，是隔离的

  • Questions about ADUM3070

    I have some questions about ADUM3070.

    Since I don't have experience using isolated DC/DC,

    It would be great if anyone could give me some advice.

    (sorry to ask many questions at the same time)

    #1 Question,

    I'm trying to calculate Transform ratio…

  • Maximizing efficiency at 5 mA while using ADuM3070

    Hi,

    ADuM3070 datasheet contains following efficiency graph:

    I plan to use 5V input voltage and 3.7V output voltage with 5mA maximum (1.5mA typical) load current. I would like to create effective isolated power supply for light loads (1-5 mA). Could…

  • Current limiting for ADUM3070

    Hi there,

    I checked out the behavior of current limiting on ADUM3070 Evaluation board.

    But I noticed the performance is a bit different from what I expected.

    The datasheet says it works with cycle by cycle during the short circuit(2msec), but I could…

  • ADUM3070 Output Voltage

    Hello:

    I have a question about transformer T1 which are listed in Table 13 and Figure 31 of the data sheet.

    I did check the data sheet of the transformer JA4631-BL.

    The output voltage of JA4631-BL is described as 3.3V to 5V.

    Is it possible to output…

  • RE: Split Isolated Supply with isoPower query(SR#: 1204350)

    Q 

    Is it possible to create a split isolated supply with the isoPower devices
    (i.e. ±3.3V or ±5V).

     

    A 

    This can be done one of two ways.

    1) Use the ADuM347x or ADuM3070.  These devices use external transformer
    so multiple windings…
