Claim 2:
3. A method of minimizing a parasitic resistance of an output capacitor of an LDC, comprising:
connecting N DC-DC converters in parallel to configure an N-phase power circuit, and commonly connecting one output capacitor to an output of each phase DC-DC converter of the N-phase power circuit, wherein each phase DC-DC converter is interleaved with a phase delay of 360°/N, in which N is a natural number greater than 1;
deriving a frequency f_im leading to a lowest impedance of the output capacitor commonly connected to the output of each phase DC-DC converter;
calculating f_im/N to calculate a shared frequency f_sh of each phase by dividing the derived frequency f_im by N; and
controlling the DC-DC converter of each phase by switching at the calculated shared frequency f_sh of each phase.
