Hi Jgirgis,

All isolated supplies will have some level of interference, but the ADUM5020 mentioned above would be a good step in the right direction. There is quite a bit of reference material on the product landing page:

Both ADUM5020 and ADUM5028 should be released already.

You can find SCH and LYT examples on user guides of Eval Boards.

Hi Paul,

Any idea on what the combined load of the 20 - 50 VFDs is? The ADM2587E can drive a network with a total of 32 unit loads (12kohm) present. If you require to add additional power in order to drive this network, I would expect the network to have…

In the past I have heard of applications using a metal shielded enclosure but not specifically using a ferrite sheet.  The new ADuM5020 can be used and does not need shielding or stitching capacitance to achieve CISPR22 Class B emissions.

Hi Belaj, 

The quick answer is yes. The ADuM5000 can provide 60mA @ 3.3V isolated power. There are some other part and package options available depending on your application needs. So to say it with package and HV rating options, the ADuM5000/ADuM6000 can…

Hi Snow,

The ADM2587E only has 15 kV HBM ESD protection on the Bus pins. It does not have IEC61000-4 levels of transient protection. In order to achieve some of the specs above it would require the use of external protection components. Please see https…

Vbus2 is a 5V power input. 

If you want to create a bus powered application, you will have to supply an additional isolated DC/DC converter.  We have chip scale converters that will work in a limited way, such as the ADuM5000 and soon the…
