Hello I am designing a battery operated circuit and it consists of one pic 18f25k20 chip and an oled display. Here is my question,
The mcu is preferably works at 1.8v for power saving, and oled runs at 3.3v I made a quick search on the net, it seems not possible to make oled run under 3.3v because of internal boost pump so I have to use dc to dc converters.
One option is to use two AA batteries in parallel and use two step up converters
Second option is two AA batteries in series and use one step up and one step down converter
Which one is more convenient? Or any other sugeestions?
