BIOSTAR X370GT7 Motherboard Review

Circuit Analysis




The X370GT7 looks good in the nude.





Hot damn! That is an expensive VRM; it uses all International Rectifier control and power stage hardware. It starts off with the fully digital IR35201 working in 6+2 phase mode. Four of the six main phases are routed to four IR3599 doublers, which then output to two IR3555.


The IR3555 are International Rectifier's second-generation of 60A fully integrated power stages. They are some of the highest rated power stages on the market. I don't know much about the inductors, but the capacitors are rated 5K. The SOC rail gets two PWM channels, which are then routed to two IR3599, and then to four IR3555M.




An Anpec APW7120 single phase PWM with driver output to two Sinopower SM4377 PowerPAK MOSFETs for a single phase memory VRM.
