Intersil ISL6247
The ISL6247 provides microprocessor core-voltage regulation by driving up to four interleaved synchronousrectified buck-converter channels in parallel. The reduction in ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area. The ISL6247 multi-phase controller together with ISL6207 gate drivers forms the basis for a portable power supply solution to power Intel’s next generation mobile microprocessors.| Part No. | ISL6247 |
