1. A power saving apparatus in an appliance, comprising:
- a DC power supply output unit that outputs a DC voltage of a predetermined level by converting an AC power supply or a battery voltage;
a main DC/DC converter that supplied a plurality of operating voltages to a corresponding plurality of devices by converting the DC voltage or the battery voltage;
a micro-controller that receives user entered power management data;
a plurality of power switches controlled by the micro-controller that selectively disconnect each of the plurality of devices to carry out a power saving function;
a CPU DC/DC converter that supplies a CPU voltage to a CPU by converting the DC voltage or the battery voltage outputted from the DC power supply output unit; and
an LCD inverter that supplies a LCD with a driving voltage by converting the DC voltage or the battery voltage, wherein the CPU voltage and the driving voltage are each adjusted according to a user'"'"'s selections in order to carry out the power saving function.
