We are looking for professional help to design a compact power supply (like in the pictures).
The power supply will be part of a customized PCB and has to meet security standards (EMC/CE/UL).
It should be a transformer based switching power supply with an efficiency of >70% (e.g. based on OB2535). Input power will be ~80-250VAC and output should be 5VDC (~3W) like in standard USB-chargers.
Main task is to provide a shematic, BOM as well as transformer data.
The Circuit should be low cost and very compact so every part size/price matters but could be discussed at any time.
We looking for someone who has a professional background at designing power supplies and willing to discuss the best solution.
