Gigabyte X99-UD3 Motherboard

Voltage Regulator

The CPU voltage regulator circuit of the Gigabyte X99-UD3 has six phases for the CPU. The voltage regulator is controlled by an IR3580 chip, using a digital design. Each phase uses one IR3556M integrated circuit, which contains both the “high-side” and the “low-side” MOSFETs.
