Claim 0:
1. An apparatus for minimizing a parasitic resistance of an output capacitor of a low-voltage DC-DC converter (LDC), comprising:
an N-phase power circuit configured by connection of N DC-DC converters in parallel between a high-voltage (HV) battery and a low-voltage (LV) battery, in which N is a natural number greater than 1; and
one output capacitor commonly connected to an output of each phase DC-DC converter, wherein each phase of the N-phase power circuit is controlled in an interleaving manner which delays a phase by 360°/N, and
wherein each N-phase power circuit is controlled by switching at a frequency equal to f_im/N, in which f_im is a frequency at which the parasitic resistance of the output capacitor is minimized.
