The ISL6557A is a multi-phase PWM controller for core-voltage regulation. It drives up to four interleaved synchronous-rectified buck-converter channels in parallel. The multi-phase buck converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. Lower ripple results in lower total component cost, reduced dissipation, and smaller implementation area. The ISL6557A also features Dynamic-VID™ technology, allowing seamless on-the-fly VID changes with no need for any additional external components. It provides fast and reliable dynamic VID changes with no output voltage overshoot or undershoot. The RGND and VSEN pins provide inputs for differential remote voltage sensing to improve regulation and protection accuracy.
