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 capac-
itors to the CPU are met, the specification of +40, -70mV at the capacitors will also be met.
4. Includes gate current.
