A low voltage DC converter for an eco-friendly vehicle comprises: a first DC-DC converter lowering a second voltage lower than a first voltage supplied to a driving motor of an eco-friendly vehicle to a third voltage; a voltage regulator outputting a fourth voltage lower than the third voltage; a controller operated by responding to the fourth voltage; and a second DC-DC converter converting and outputting the first voltage to the third voltage by responding to an output signal of the controller. The output voltage of the second DC-DC converter is supplied to the voltage regulator.
