ISL6307ACRZ
数据手册.pdf超高带宽的6相PWM控制器，具有8位VID代码，能够精确的RDS （ ON）或差分DCR电流检测的 Ultra-high bandwidth 6-Phase PWM Controller with 8 Bit VID Code Capable of Precision RDSON or DCR Differential Current Sensing
The ISL6307A controls microprocessor core voltage regulation by driving up to6 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area.
