1. A system for controlling a low voltage DC converter of a vehicle, the system comprising:
the low voltage DC converter configured to step down a voltage of a first battery and output an output voltage;
a blower configured to operate using the output voltage of the low voltage DC converter as a power supply voltage; and
a low voltage DC converter controller configured to receive information on whether the blower operates and an output setting of the blower, and control a magnitude of the output voltage of the low voltage DC converter, based on the received information on whether the blower operates and an output setting of the blower;
wherein when the blower is in an operating state and the output setting of the blower is greater than a preset threshold, the low voltage DC converter controller controls the low voltage DC converter such that the low voltage DC converter constantly outputs a preset output voltage value.
