Claim 9:
10. A method for outputting a constant voltage using a low voltage DC-DC converter of a vehicle, the method comprising:
dropping, by a first DC-DC converter included in the low voltage DC-DC converter of the vehicle, a second voltage lower than a first voltage supplied to a drive motor of the vehicle to a third voltage;
regulating, by a voltage regulator included in the low voltage DC-DC converter, the third voltage and outputting, by the voltage regulator, a fourth voltage lower than the third voltage;
operating, by a controller included in the low voltage DC-DC converter, in response to the fourth voltage;
converting and outputting, by a second DC-DC converter included in the low voltage DC-DC converter, the first voltage into the third voltage in response to an output signal of the controller; and
supplying, by the second DC-DC converter, the third voltage to the voltage regulator.
