We are designing AC/DC converter using MPS020-5 power IC to get 3.3Vdc @ 0.6A output, just as the attachment added shows.
We will be doing FCC certification and comply with UL 60950-1 safety criteria. For that, we have added fuse and MOV as input protection circuit and Pi filter (after rectifier) for EMI/EMC and to remove unwanted noise (complete introduction and classification of filters and applications http://www.apogeeweb.net/article/35.html).
Do I still require to add additional filter circuitry on input side i.e. X2 cap, CMC etc. for noise removal or provided filter circuit will take care of all?
Also, let me know if it is required to change any component value in current design.
Awaiting for your valuable inputs.
