Description

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.

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.
