The power supply device includes a switch control circuit, a charge control circuit, and a discharge control circuit. The switch control circuit controls switches so that electrical power is charged into an inductor, discharged from the inductor, and distributed to first and second capacitors in a time-division manner based on a switching cycle. The charge control circuit controls the amount of electrical power to be charged into the inductor based on a first amount of error between a first output power supply voltage and its target value and a second amount of error between a second output power supply voltage and its target value. The discharge control circuit controls a distribution ratio at which the electrical power discharged from the inductor is distributed to the first and second capacitors based on the ratio between the first and second amounts of error."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device with shared inductive elements under switch control","description":"A power supply device is responsive to load changes.
