Abstract:
An interleaved multi-phase power supply with a plurality of DC-DC converter ICs. Each DC-DC converter IC has a current sharing pin, and the current sharing pins of the plurality of DC-DC converter ICs are connected together. Each DC-DC converter IC receives a feedback voltage signal to compare with a reference voltage signal to generate an error voltage signal as a reference of an output current of the corresponding DC-DC converter IC. And each DC-DC converter IC has a mismatch voltage regulation module regulating the error voltage signal to be equal to an average of error voltage signals of the plurality of DC-DC converter ICs.
