The switching circuit includes multiple switching elements, an inductor, and a capacitor. The control circuit compares an input voltage of the switching circuit with a predetermined threshold voltage set for an operation switch, and controls the switching circuit to perform the operation switch between at least two power control operations based on a comparison result. The at least two power control operations includes at least two of a buck operation, a buck-boost operation, or a boost operation. The control circuit further performs an inrush current restriction operation in response to the operation switch in order to restrict a flowing of an inrush current to one of the switching elements, which turns on and outputs the input voltage through the inductor in response to the operation switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply device, electric device, and vehicular device","description":"A switching power supply device includes a switching circuit and a control circuit.
