An integrated power supply includes a first low voltage DC-DC converter (LDC) that converts supply power to a first output voltage and provides the first output voltage to a first auxiliary battery and a first electric load connected to each other in parallel; a second LDC that converts the supply power to a second output voltage and provides the first output voltage to a second auxiliary battery and a second electric load connected to each other in parallel; and an integrated controller that controls the first LDC and the second LDC to change output voltages of the first LDC and the second LDC. The first auxiliary battery and the second auxiliary battery are connected in series, and when the first LDC fails, the second LDC outputs a second increase output voltage that is higher than the second output voltage under control of the integrated controller.
