Circuit Analysis




Another interesting motherboard in the nude.





The VRM on the Z170X-Designare is an 8+3 phase VRM and uses custom branded Power inductors and 10K black polymer solid capacitors.




The Intersil ISL95856 is a 4+3 phase hybrid PWM that provides 4+3 phases that are then doubled to 8+3 phases, for the CPU VCore + integrated GPU. The ISL95856 has three integrated drivers, so GIGABYTE adds four more to support all the phases. Each phase uses a Vishay SiRA12 for the high-side MOSFET and a Vishay SiRA18 for the low-side. The MOSFETs are PowerPAKs. Phases are doubled by doubling the number of MOSFETs on each driver. The VCCIO, VCCSA, and other rails for overclocking come from a linear regulator circuit and a few LDOs.




The memory VRM uses a Richtek RT8120D PWM controller with integrated driver and two SiRA12 low-side MOSFETs and one SiRA12 high-side MOSFET.
