Abstract
A DC-DC converteraccumulates power generated by a power source in a power storage element, converts power from an input into a predetermined voltage to supply the predetermined voltage to a load connected to an output, and is activated to start power feeding when an input voltage exceeds Vd. A power source control sectionis connected to the output of the converterto obtain power to operate, and controls the power supply to the load while changing an operation mode according to the power source energy. The sectionis activated by the start of the power supply by the converter to operate in a low power-consumption mode with only the detected power source energy monitor, and starts the power supply to the load when the energy exceeds a level in which the input voltage becomes equal to Vdhigher than Vd
