ASUS A88X-PRO Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS A88X-PRO has six phases for the CPU main voltage (VDD or Vcore) and two for the CPU memory controller (VDDNB). Therefore, it uses a “6+2” configuration. The voltage regulator is controlled by an ASUS DIGI+ ASP1107 integrated circuit. Each phase is driven by one NTMFS4C09N and two NTMFS4C06N transistors.
