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, the converter will be in compliance with Intel’s
VRM 8.4 specification of +50, –80mV. If Intel specifications on maximum plane resistance from the converter’s output
capacitors to the CPU are met, the specification of +40, –70mV at the capacitors will also be met.
