Circuit Analysis

ASRock Fatal1ty X99 Pro Gaming i7 Motherboard Review 18 | TweakTown.com

The PCB silkscreen is unique, and I like how ASRock has smoothened out most of the front facing PCB by moving many components to the rear of the PCB.

The main CPU VRM is made up of 12 phases. Each phase uses a 60A inductor, and the output capacitor bank contains ASRock's gold 12K capacitors. The PWM controller is an Intersil hybrid digital ISL6379 six phase model.

ASRock is using Fairchild Semiconductor FDMS3660S PowerTrench Power Stages that contain both the high-side and low-side MOSFETs. On the back of the PCB are six Intersil ISL6611A doubler/dual driver units that take the six PWM channels from the PWM controller and double them to twelve.

Each memory VRM uses a UPI UP1674P analog PWM, two Fairchild FDMS3660s, and a few 12K gold polymer capacitors.
