    摘要: A power supply control device includes a boost type power supply controller boosting an input voltage, a step down power supply controller reducing an output of the boost type power supply controller to output an output voltage, a first control loop including the boost type power supply controller, and a second control loop including the step down power supply controller, wherein the output voltage is controlled by the second control loop during a predetermined period beginning after the power supply control device enters a power-on state, and wherein the output voltage is controlled by the first control loop after the predetermined period passes.
