Description:The ISL78226 is a 6-phase, bidirectional, synchronous PWM controller designed to perform power conversion between 12V and 48V buses up to 3. 75kW at >95% conversion efficiency. One ISL78226 supports both Buck and Boost power conversion enabling a compact and robust design with minimum components. ISL78226 regulates both voltage and current to control power transfer from bus to bus. The multiphase architecture uses interleaved timing to support up to six parallel power stages per ISL78226.
