Feature Description

6.3.1

Voltage Regulator Assignment and Powergood Comparator Logic Assignment

(External Voltage Regulator or Load Switch) for Skylake and Kabylake Platform

For the Skylake and Kabylake Power Map implementation, the five PMIC voltage regulators and LDO1 are

assigned with the low -voltage rails merged or split according to the configuration. For the Volume

(merged low voltage rails) configuration six external load switches are controlled and monitored by using

six powergood comparator logic blocs.
