LPC17 and 15V supply

[pcbatterij]

Hey all,

I was wondering if it would be possible to supply the LPC17 board with 15V? can I take the risk or do I need to buy another transfo or build a voltage divider?

cheers

Not recommended. About 8-9V DC would be ideal. The 78xx series need about 3V on top of their rating to properly regulate. If you go above that, the regulator will have to get rid of all the excess power by generating heat. So multiply the excess voltage with the amount of amps drawn....and you know with how many watts you are heating your room :whistle:
