pcbatterij Posted December 1, 2011 Report Share Posted December 1, 2011 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 Jef Quote Link to comment Share on other sites More sharing options...
Shuriken Posted December 1, 2011 Report Share Posted December 1, 2011 (edited) 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: Edited December 1, 2011 by Shuriken Quote Link to comment Share on other sites More sharing options...
