This DC/DC converter is specially modded by the Fuel Cell Store for low voltage operation for single cell or small fuel cells. With an input voltage as low as 0.3 V and a user selectable output voltage of either 3.3V or 5V, this DC/DC is well suited for when you would like to use a single cell fuel cell (such as the Mini PEM Reversible, Mini PEM Fuel Cell, or Flex-Stak) to replace or even charge batteries.
The input voltage can range from 0.3 V (good for single cell fuel cells) up to 5.5 V. The output is 5V at 600mA Max (default) or 3.3V at 200mA max (solder jumper adjustable).
