No mgnetics


In our new design we will use W5500. We will need also on board ethernet switch to connect our modules in parallel. We would like to use transformerless connection from W5500 to switch chip, which we have not choosen yet. Do you think one of the circuits represented in Micrel’s app. note … an-120.pdf could be used with W5500?

Thank you in advance



The connection without transformer maybe not impossible.
But, These connection is not garantee because We have not test yet.
So Sorry!

The test connection w/o transforme will be progressing and issue the result and techinical consideration as soon.

If you can test to it, I will thank you to let me know the result.

Thank you.
