This is a bit 'geeky' but may be useful to any cubesat builders reading the
Freescale have a nice video on You Tube showing their new ultra low voltage
DC-DC converters being used to charge a Lithium ion cell.
>From a single solar cell with an onload voltage of just 349mV they are
charging a lithium ion battery at 3.82V at 63mA with about 83% efficiency.
Sorry for the bandwidth. Geek time over. -
This may be useful copied to the cubesat reflector.
