ECS Z77H2-AX Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ECS Z77H2-AX has 12 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 “12+2+1” configuration. The voltage regulator is controlled by a uP1618A integrated circuit, using a digital design.
