Abstract
A control method for communicating with an external device includes the steps of: when the external device is coupled to a connector, receiving a device existence voltage from the external device; generating a first control signal and a second control signal according to the device existence voltage; coupling a first voltage source or a second voltage source to the connector according to the first control signal, such that a first voltage of the first voltage source or a second voltage of the second voltage source is used as a supply voltage of the external device; and coupling a third voltage source or a fourth voltage source to an output node according to the second control signal, such that a third voltage of the third voltage source or a fourth voltage of the fourth voltage source is used as a tunable output voltage at the output node.
