A 5V/5mW power by light (PbL) power supply has been designed and developed. The design is based on a 50mw 800nm laser diode a segmented GaAs photocell and a DC/DC converter which acts as a voltage regulator. This paper discusses the system concept and elements as well as the measured efficiencies of the components and the system configuration. The paper also discusses the scalability of the design concep
