Abstract

The present disclosure discloses a multi-output voltage conversion apparatus. An input switch circuit couples a first terminal to a voltage input terminal to perform a charging procedure or to a ground terminal to perform a discharging procedure. An inductor generates a current according to a voltage difference between the first and the second terminals. Each of output circuits couples the second terminal to a corresponding output terminal generating a corresponding output voltage. A control circuit determines a selected output circuit to be enabled from candidate output circuits having the corresponding output voltage being lower than a corresponding lower limit threshold value, controls the input switching circuit to perform the charging procedure, determines that the charging procedure is finished, controls the input switch circuit to perform the discharging procedure and determines that the discharging procedure is finished so as to perform the determining procedure again.
