Abstract:
1. An apparatus for controlling power consumption in a Personal Digital Assistant (PDA) phone, the apparatus comprising: a PDA controller for applying at least one of a first signal and a second signal to a PDA voltage module, for sensing a voltage of a first capacitor which voltage corresponds to the applied first or second signal, and for operating at the voltage of the first capacitor; and the PDA voltage module in which a first resistor is shorted or open corresponding to the applied first or second signal, and a voltage applied to the first capacitor corresponds to shorted or open state of the first resistor, wherein the PDA voltage module comprises: a switch for switching on when the first signal is input and for switching off when the second signal is input; the first resistor connected to the switch, which is shorted when the switch is turned on and which is open when the switch is turned off; a second resistor connected to the first resistor in parallel; a third resistor connected to the second resistor in series; and a voltage applying unit for changing the voltage applied to the first capacitor using a voltage of the second resistor corresponding to the open or shorted state of the first resistor.
