current. The boost converter is capable of
providing up to 500mA to 12V output from a single
cell super capacitor or a battery at 2.7V. A
linear supercapacitor charge is also integrated with a very high accuracy CV voltage.
The output voltage of boost can be adjusted by
external resistor divider. All three power
modules are packed into a single ES0P8 and
