Hi All, back with more newbie questions:
I'm working on a project with an ATmega128. From the data sheet, this uC has an op. voltage of 4.5 - 5.5 Volts. I will be running this project off of a cell-phone battery, (Nokia BL-4C, here)
which provides in the area of 3.7 volts. Obviously, I will need to do something to step the lower-voltage up to a usable level. Presumeably, there is some basic circuit, that has existed since the dawn of time, to do this. What is it? What am I looking for here? Is is a transformer? A boost converter?
Thanks in advance..
