X370 PRO4 Circuit Analysis





The X370 PRO4 reveals some interesting things when we remove the heat sinks.




The VRM is in a 6+3 phase configuration, and it uses an Intersil ISL95712 PWM controller which is designed for AMD's platform. The PWM controller has two integrated drivers for the CPU VCore part and one more for the SoC rail.


ASRock adds one more ISL6625A for the VCore and two more for the SoC rail. ASRock doubles the number of power stage components on the CPU VCore rails to get six phases. MOSFETs are the Sinopower SM4336 for the low-side MOSFET and SM4337 for the high-side. The SoC phases get two low-side one high-side configuration while the VCore part gets one low-side and one high-side MOSFET.




The memory VRM looks like it's using two phases and it's controlled by an Anpec APW8720.
