I'm trying to build a Tiny15 project with two AAA-cells. I plan to use the Tiny15L directly as a miniature boost converter, so that my Vcc can be higher than the battery (mostly for other chips in the project).
After I bought the Tiny15Ls that I need, I decided to use two AAA NiMH cells; they would be OK at full charge (2.8V) but they fall short when partly discharged (2.4V).
Does anyone know if the Tiny15 will start dependably at 2.4V? I don't plan to do anything at 2.4V except get the PWM going. If 2.4V simply isn't going to work, any other ideas?
Space is at a premium here; the whole project is about 40mm long and 20mm wide.
