FAN5091 Overview
The FAN5091 is a synchronous multi-slice DC-DC controller IC which provides a highly accurate, programmable output voltage for all high-performance processors. Two interleaved synchronous buck regulator slices with built-in current sharing operate 180° out of phase to provide the fast transient response needed to satisfy high current applications while minimizing external ponents.
