Hi Happy New Year I would like my BBB to be shot down correctly via shut down or halt command if power into BBB is interrupted ( and by doing that avoid corruption of my SD card). So, I have two supercapacitors - 10F 2.7v connected in series, what I am looking for is a dc/dc converter ( stepUp) to keep output at 5V even when voltage from capacitors is slowly dropping. I need about 6 sec for system to shut down correctly from the moment of power shortage . So up to 500 mA stepUp voltage regulator. Any idea which one to use?? Anybody worked on this kind of design?? Thanks in advance Robert
