| | FAN5098 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 remote voltage sensing and 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 0.5%. 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. | | FAN5098 Datasheet and Application Notes | | | Parameter | Value | | Product status | Full Production | | Pricing* | $1.76 | | Package type | TSSOP | | Leads | 24 | | Packing method | RAIL | | Products related to FAN5098 | | FAN5098MTCX FAN5098MTC |
