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
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…
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…
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…
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…
