FAN5093

The FAN5098 is a synchronous two-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for the AMD ® Hammer™ processor. 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 components.namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The FAN5098 features Programmable Active Droop for transient response with minimum output capacitance. It has integrated high-current gate drivers, with adaptive delay gate switching, eliminating the need for external drive devices. The FAN5098 uses a 5-bit D/A converter to program the output voltage from 800mV to 1.550V in 25mV steps with an accuracy of 1%. The FAN5098 uses a high level of integration to deliver load currents in excess of 50A from a 12V source with minimal external circuitry.

The FAN5098 also offers integrated functions including Power Good, Output Enable/Soft Start, under-voltage lockout,over-voltage protection, and adjustable current limiting with independent current sense on each phase. It is available  in a 24 pin TSSOP package.
