The CPU voltage regulator circuit of the Gigabyte H170N-WIFI has five phases for the CPU. The voltage regulator uses an Intersil ISL95858 controller chip (digital design). Each phase uses two MOSFETs, but we were not able to identify the models.
The Gigabyte H170N-WIFI uses high-end “black” solid capacitors and all coils on this motherboard are ferrite ones.
