The CPC1822 is a monolithic photovoltaic string of
solar cells with switching circuitry. When operating
in sunlight or a bright artificial light environment the
optical energy will activate the cell array and generate
a voltage at the output. The solar cells are capable
of generating a floating source voltage and current
sufficient to drive and power CMOS IC's, logic gates
and/or provide "trickle charge" for battery applications.
