Arduino DC-DC converter? Answered
I have an Arduino project which drives a set of 12V LEDs using NPN transistors, I had been using the linear regulator on the Arduino to convert 12V to 5V for the Arduino and Ethernet shield, however I have some IL1205 DC-DC converters which could also be used, personally I think the IL1205s are the better option as they seem to dissipate less heat then the regulator on the board.
Are there any other solutions to this, It would be ideal of I could power the entire project from a single 12V power supply, it also has to run continuously so must either produce little heat or be easy to dissipate the heat away from.
Also because of the circuit I have to bridge the -Vin and -Vout terminals of the converter (for the transistors to work properly) I assume there is no problem in doing so.
Any help is greatly appreciated.
