Gigabyte Z77X-UD3H Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the Gigabyte Z77X-UD3H has six phases for the CPU main voltage (Vcc a.k.a. Vcore), two for the CPU VSA voltage (memory controller), and one for the CPU VTT voltage (PCI Express and DMI interfaces). Therefore, it uses a “6+2+1” configuration. The voltage regulator is controlled by an IR3567A integrated circuit, using a digital design.
