12vdc from 5vdc

[TravisR100]

I have a board that requires a 5vdc 2a supply. I have a switching power supply for this. The board also requires a 12vdc supply at 10 milliamps. The two have to be isolated. Could I simply use this?

It is a Cosel SUS1R50512C. It's described as Compact Multi-Purpose Isolated DC-DC converter.

It would seem to be the smallest, cheapest solution.

HI Travis,

Have you considered pricing Walwarts at Wally World?

Input 115 VAC, output 12 VDC @ 200-300 ma.

Yes, I've had several people suggest that. I prefer not to clutter my cabinet with a wall wart nor do I want to have to put an AC outlet in the cabinet.

The one in your post look like it would do OK, the problem for you with the Digi-Key one is that it is not isolated.
There are IC's that operate in a charge pump fashion to get it also, but most are not isolated either.
