Ground Reference
When driven high, this input will disable the
Voltage Regulator Module output and the
output of the module will float.
Power Good is driven low when the VRM
output is not within valid levels.
Sense is provided for the regulator to correct
for voltage drops across the connector and
motherboard powerplane.
