Hello,
I am trying to use ADuM5028 to supply gate driver with isolated 5V, but I have read in the datasheet in page 11 that "It is recommended that the ADuM5020-3BRWZ and the.ADuM5028-3BRIZ are only used for 3.3 V input to 3.3 V operation, therefore…
Both ADUM5020 and ADUM5028 should be released already.
You can find SCH and LYT examples on user guides of Eval Boards.
I would like to use ADUM5020/ADUM5028 for a RS-485 circuit. With ADM2795E transceiever.120Ohm Termination, 3.3V bus and 500kbit/s.
Do you have an application note or example design about power calculations?Thanks for any help.
Jimbles:
You don't need to use stitching capacitance with the ADuM5028, the use of ferrites alone and following the layout in the eval board should meet CISPR22 class B emissions if care is taken with a very short wires from a power source like a battery…
Hi Javier,
It may be possible with very careful layout to meet Class A on a two layer. Best for emissions would be to use a 4-layer board and use the inner layers to create stitching capacitance.
There may be an easier way to meet emissions targets on…
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,
6.5V on Vin1/Vin2 is an absolute maximum rating only. The main obstacle to operating the LDO at 5V in would be thermal limitations of the package (there could be up to an extra 0.25W if both sides are operated this way). Also reliability, production…
