H370N WIFI Circuit Analysis
The H370N WIFI reveals its secrets with the heat sinks removed.
The VRM is in a 4+2 phase configuration for the VCore and iGPU phases. The Intersil/Renesas ISL95866 offers 4+3 phase output and one integrated driver on the iGPU output and two on the VCore output. GIGABYTE adds three ISL6625A drivers to control the remaining phases. ON Semiconductor 4C06N are used for the low-side and 4C10N for the high-side. The CPU VCore phases use two low-side MOSFETs per phase and one high-side MOSFET, while the iGPU phases use one of each.
He remaining low-side MOSFETs that are doubled for the VCore are on the back of the PCB. Secondary rails are provided by linear regulators and much smaller switching regulators.
