Abstract
A power source device includes a storage capacitor, a voltage detection circuit, input terminals, and output terminals, further includes: a boost circuit which converts a storage power provided to the input terminals to a boosted power under the condition that a stored voltage becomes equal to or greater than the predetermined voltage, and outputs the boosted power from the output terminals; and a MOS transistor which controls a supply of the boosted power to a load. One of the input terminals is connected to a gate terminal of the MOS transistor, and one of the output terminals is connected to a source terminal of the MOS transistor. The MOS transistor turns on to convert the storage power to the boosted power in the boost circuit, while the MOS transistor turns off not to convert the storage power to the boosted power in the boost circuit.
