FAN5193 Description
The FAN5193 is a synchronous multi-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for all high-performance processors. Two interleaved synchronous buck regulator phases 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.
