The application is a tiny robot which will hopefully draw in the neighborhood of 50mA undle normal conditions and maybe 100mA in a worst case scenario.
5V boost chip: MAX856 ... good choice? I like it on paper, low parts count.
Power source: One 2500 mAh NiMH cell... good choice? Sounds better than two 750 mAh AAA cells.
Would it be a wise idea to "gang" a 12V boost regulator on the output of the 5V boost circuit? Or maybe someone knows of a 12V boost regulator that can run on only one or two cells?
