Description

The FAN5056 is a synchronous mode DC-DC controller IC which provides a highly accurate, programmable set of output voltages for multi-voltage platforms such as the Intel Pentium III, and provides a complete solution for all Intel VRM8.5 CPU applications, and for other high-performance processors. The FAN5056 features remote voltage sensing, independently adjustable current limit, and a proprietary wide-range Programmable Active Droop™ for optimal converter transient response and VRM8.5 compliance. The FAN5056 uses a 5-bit D/A converter to dynamically program the output voltage during operation from 1.05V to 1.825V in 25mV steps. The FAN5056 uses a high level of integration to deliver load currents in excess of 28A from a 5V source with minimal external circuitry. Synchronous-mode operation offers optimum efficiency over the entire specified output voltage range. An on-board precision low TC reference achieves 0.8% voltage regulation without expensive external components. The FAN5056 includes linear regulator controllers for Vclock (2.5V),Vnorthbridge (1.8V) or Vagp (selectable 1.5V/3.3V), and Vadjustable (1.2V nominal) each adjustable with an external divider. The FAN5056 also offers integrated functions
