We are designing a circuit which should be powered directly from mains (230VAC), and have in the previous design used a normal transformer.
But in the next design we would like to use an AC-DC converter, since this could make our design more flexible with possible input of 120VAC to 230VAC 50/60Hz.
The output of the converter is preferred to be 5VDC but could be higher.
I have found the bp5048-15 from ROHM, which would do the job.
Does anyone have a better or cheaper solution?
EDIT: wall adaptor is not an option, we need to supply the product directly with mains.
