I am trying to build a 2.7v power supply for my arduino on a breadboard. I will be running it at 8 MHZ which should be fine at 2.7v.
Anybody have a favorite DC/DC converter IC that will work at 2.7v ish that is easy to build on a breadboard? I tried to build a DC/DC booster on a breadboard and failed miserably. I think it switches so fast that you really have to use a PCB or vector board. I successfully built one of LadyAda's minty booster kits and it worked wonderfully.
I am hoping to power from a Lithium Ion battery which will run anywhere from about 2.7v to 4.2v. I would just skip the DC/DC converter all together, but I am taking readings from an analog pin, and I think allowing the voltage to swing that much will really screw up the analog to digital converter readings.
Any advice would be greatly appreciated.
