Abstract
A boost DC-DC converter includes: an input terminal; an output terminal; a first boost circuit configured to generate, from an input power to the input terminal, a first boosted power having a higher voltage than a voltage of the input power, and outputs the generated first boosted power from the output terminal; a second boost circuit configured to generate, from the input power, a second boosted power having a higher voltage than the voltage of the input power; and a storage capacitor configured to store the second boosted power as a storage power, and supply the storage power to the first boost circuit as an operation power source. The first boost circuit is configured to start a boost operation with the storage power when a voltage of the storage power is equal to or higher than a minimum operation voltage of the first boost circuit.
