ASUS Z87-A Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS Z87-A has eight phases for the CPU. The voltage regulator is controlled by ASUS DIGI+ ASP1251 chip, which uses a digital design. Each phase is driven by two NTMFS4937N MOSFETs, which provide a maximum RDS(on) of 6 mΩ.
