INTEGRATED RESONANCE AND POWER FACTOR CORRECTION CONTROL INTEGRATED CIRCUIT AND POWER CONVERTER

摘要

Provided are a resonance and PFC integrated control IC and a power converter. The resonance and PFC integrated control IC includes an interleave PFC control block and a resonance control block. The interleave PFC control block is configured to control first and second switches of an interleave switching converter and correct a power factor. The interleave switching converter includes a first converter comprising the first switch and a second converter comprising the second switch, and the first converter and the second converter are connected in parallel. The resonance control block is configured to resonate and control a Direct Current (DC)-DC converter that receives and converts the output of the interleave switching converter.
