If you can afford the extra 1/2W, a simple linear regulator generating the 5V from the 12V will do. If not, use a shielded switcher and filter it well. There seems to be different pinouts for different FE-5680A part numbers, too.

Looking at packaging and the housing it does look new. I have not powered it up because of +5 Volt on pin 4. Does any one know its purpose and is there a power up sequence. Any help will be appreciated.
