I am currently working on a project where I am Designing a single transistor forward converter in class.
Project as of now:
120VAC rectified (to ~168VDC) then dropped to 5VDC with a max current of 1A via forward converter
I have a concern that I am going to need electrical isolation for my micro-controller that I am using to control the duty cycle of the converter (I decided to use the boarduino with the Atmega 328p chip). I am not sure of the best way to isolate the micro-controller though. I have seen on mouser some small voltage isolation transformers that seem like they may be promising for such a task, but I would like a second opinion because none of my professors know much about it and I would like to get this project done ASAP. Here is a link to the small voltage transformer I was talking about:

I also wanted to know if there was a good place that sold pre-made three winding toroids for a forward converter. I am winding my own at the moment, but I would like a backup plan if mine does not work for whatever reason it may be.
Please let me know if you have any other advice for a young Engineer.
Thanks in advance,
-Steve
