FAN5056MV85 - High Performance Programmable Synchronous DC-DC Controller

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.

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.
  • Overcurrent protection using MOSFET sensing.
  • Overvoltage protection including startup.
  • 85% efficiency typical at f.
