ECS Z87H3-A2X Extreme Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ECS Z87H3-A2X Extreme has 12 phases for the CPU, controlled by an ISL6367 chip, which uses a hybrid design (i.e., analog) and provides six phases. Each of these phases is then doubled by the use of an ISL6611A chip, creating the 12 phases that are available. Each phase uses an IRF8308MPbF MOSFET, with a maximum RDS(on) of 2.7 mΩ, and an IRF8327SPbF MOSFET, with a maximum RDS(on) of 5.1 mΩ.
