ISL6247 Overview
® ISL6247 Data Sheet June 2003 FN9113 CO NF ID EN TIA L A Mobile Multi-Phase PWM Controller with Precision Current Sensing The ISL6247 provides microprocessor core-voltage regulation by driving up to four interleaved synchronousrectified buck-converter channels in parallel. Multi-phase buck converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. The...
