A Scalable Multiphase Current-Mode Buck Controller With Sub-Milliohm DCR Current Sensing and Synchronized Overcurrent Protection

This article presents a scalable multiphase peak current-mode Buck controller with sub-milliohm direct current resistance (DCR) current sensing and synchronized overcurrent protection. Low DCR current sensing capability is critical in pursuing high efficiency and precise current balancing. For this...
