FAN5090 Datasheet (Fairchild Semiconductor) - Two Phase Interleaved Synchronous Buck Converter

FAN5090, Two Phase Interleaved Synchronous Buck Converter

The FAN5090 is a synchronous two-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for VRM 9.x 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
