Abstract: A power supply system for a circuit device includes a power supply unit, a switch unit and a voltage detector. The power supply unit, coupled to the circuit device via a power line, is used for supplying basic power for the circuit device via the power line, wherein the power line is coupled to the circuit device via a plurality of nodes. The switch unit, near to a node among the plurality of nodes, is coupled to the circuit device via the power line. The voltage detector, coupled to the circuit device and the switch unit, is used for detecting a voltage of the node and controlling the switch unit to be closed to allow the circuit device to receive auxiliary power via the switch unit when detecting that the voltage of the node is lower than a first threshold value.

Abstract: A power output circuit includes a charge pump, a voltage regulator, a clock generator and a voltage detector. The charge pump is used for receiving a clock signal having an operating frequency and outputting an output voltage. The voltage regulator, coupled to the charge pump, is used for outputting a control voltage to the charge pump, to control the output voltage. The clock generator, coupled to the charge pump, is used for outputting the clock signal to the charge pump. The voltage detector, coupled to the clock generator and the voltage regulator, is used for detecting the control voltage and controlling the clock generator to adjust the operating frequency of the clock signal according to a magnitude of the control voltage.
