ISL6247 A Mobile Multi-Phase PWM Controller

® 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 reduction in ripple results in fewer components, lower component cost, reduced p.
