FAN5070  
High Performance Programmable Synchronous  
DC-DC Controller  
Features  
Description  
• Output programmable in 25mV steps from 1.05V to  
1.825V using a dynamically programmable integrated  
5-bit DAC  
• Remote sense  
• Programmable Active Droopup to 200mV  
• Drives N-Channel MOSFETs  
• Overcurrent protection using MOSFET sensing  
• Overvoltage protection including startup  
• 85% efficiency typical at full load  
• Integrated Power Good and Enable/Soft Start functions  
• Meets Intel VRM8.5 specifications using minimum  
number of external components  
The FAN5070 is a synchronous mode DC-DC controller IC  
which provides a highly accurate, programmable output volt-  
age for 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 FAN5070  
features remote voltage sensing, independently adjustable  
current limit, and a proprietary wide-range Programmable  
Active Droopfor optimal converter transient response and  
VRM8.5 compliance. The FAN5070 uses a 5-bit D/A con-  
verter to dynamically program the output voltage during oper-  
ation from 1.05V to 1.825V in 25mV steps. The FAN5070  
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  
FAN5070 also offers integrated functions including open-  
collector Power Good, Output Enable/Soft Start and current  
limiting, and is available in a 20 pin SOIC package.  
• 20 pin SOIC package  
Applications  
• Power supply for Pentium® III Platforms  
• VRM for Pentium III processor  
• Programmable power supply
