Abstract:
1. A multiple output stage converter (MOSC), comprising: a first transistor, having a source/drain coupled to a first output terminal, another source/drain coupled to an inductor, and a gate coupled to a first control signal, so as to determine an on/off status of the first transistor according to the first control signal; a second transistor, having a source/drain coupled to a second output terminal, another source/drain coupled to the inductor, and an on/off of the second transistor being determined according to a second control signal, wherein the well of the second transistor is floated; a third transistor, having a source/drain coupled to another source/drain of the first transistor, another source/drain thereof coupled to a ground voltage, and a gate coupled to a third control signal, so as to determine an on/off status of the third transistor according to the third control signal; and a logic control module, coupled to the gate of the second transistor, wherein a voltage is output to the gate of the second transistor when the first control signal or the third control signal is enabled, and the second control signal is output to the gate of the second transistor when the second control signal is enabled.
