VRM Overview

Specifications

The MSI MEG X670E ACE features a 22+2+1 phase VRM configuration. These are setup in as "Duet" power stages as MSI marketing has named it, resulting in every two receiving the same PWM signal.


MSI is using a Infineon XDPE192C3B PWM controller to drive the MEG X670E ACE Master power stages.


The MSI MEG X670E ACE uses Infineon TDA21490 power stages for the 22 Vcore phases. These power stages each support a maximum of 90 A of continuous current. For the SoC phase, MSI is using two Infineon TDA21472 70 A power stages.


On one end of the VRM setup is the VDD_MISC power. This is using a MaxLinear MXL7630S 30 A for the single power stage.

MSI MEG X670E ACE has a maximum output of 1,980 dedicated to Vcore.
