Notes:
1. 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. Nominal output is offset +25mV vs. VID table.
2. Using the VFB pin for remote sensing of the converter
’
s output at the load, the converter will be in compliance with AMD
specification of V
DAC
±50mV.
