ISL78224 Overview
One ISL78224 supports both Buck and Boost power conversion, enabling a pact and robust design with minimum ponents. The ISL78224 regulates both voltage and current to control power transfer from bus to bus. The multiphase architecture uses interleaved timing to support up to four parallel power stages per ISL78224.
