REV. 1.0.1 8/7/01
Notes:
1. Steady State Voltage Regulation includes Initial Voltage Setpoint, Droop, Output Ripple and Output Temperature Drift and is
measured at the converter’s VFB sense point.
2. As measured at the converter’s VFB sense point. For motherboard applications, the PCB layout should exhibit no more than
0.5m
trace resistance between the converter’s output capacitors and the CPU. Remote sensing should be used for optimal
performance.
3. Using the VFB pin for remote sensing of the converter’s output at the load, and the appropriate droop, the converter will be
in compliance with Intel’s VRM 8.5 specification. If Intel specifications on maximum plane resistance from the converter’s
output capacitors to the CPU are met, the specifications at the capacitors will also be met.

Note:
1. 0 = processor pin is tied to GND.
1 = processor pin is pulled up to 3.3V.
