Min Operating Temp: 0 °C
Description
The FAN5071 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 FAN5071 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.
Key Features
- Output programmable in 25mV steps from 1.05V to 1.825V using a dynamically programmable integrated 5-bit DAC
- Controls adjustable linears for Vclock (2.5V), Vnorthbridge (1.8V) or Vagp (selectable 1.5V/3.3V), and Vadj (1.2V nominal)
- Remote sense
- Programmable Active Droop™ up to 200mV
- Drives N-Channel MOSFETs
