The present invention relates to an apparatus and a method for controlling an output of a power converter for an eco-friendly vehicle. The apparatus according to the present invention includes the power converter which converts a DC voltage of a high voltage supplied from a main battery in the vehicle into a DC voltage of a low voltage, a voltage sensor which measures an output voltage outputted from the power converter, a comparator which compares the output voltage with a target voltage, a fault detector which detects the fault of the voltage sensor, and a controller which calculates a duty by using the target voltage, and a voltage control ratio and an input voltage of the power converter if the fault of the voltage sensor is detected through the fault detector, and controls the switching operation of the power converter based on the calculated duty. Accordingly, the present invention can constantly control the output voltage of the power converter when the sensor malfunctions.
