According to the present invention, an integrated power supply apparatus for a vehicle comprises: a first LDC converting a supply power into a first output voltage and providing the first output voltage to a first auxiliary battery and a first electronic load which are parallelly connected; a second LDC converting the supply power into a second output voltage and providing the second output voltage to a second auxiliary battery and a second electronic load which are parallelly connected; and an integrated controller controlling the first LDC and the second LDC and changing the output voltage of the first LDC and the second LDC. The first auxiliary battery and the second auxiliary battery are serially connected. When the first LDC is out of order, the second LDC outputs a second rising output voltage which is higher than the second output voltage in accordance with the control of the integrated controller. Therefore, in case of a fail-safe, the power supply efficiency can be improved.
