ASRock X99 Extreme4 Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASRock X99 Extreme4 has 12 phases for the CPU. The voltage regulator is controlled by an Intersil ISL6379 chip, using a digital design. Each phase uses one FDMS3660S (“22CF 07OD”) integrated circuit, which contains both the “high-side” and the “low-side” MOSFETs.

The ASRock X99 Extreme4 uses 12K Platinum electrolytic capacitors from the Japanese maufacturer Nichicon, and 60 A ferrite chokes, which is an excellent configuration.
