Circuit Analysis


The Z390 Aorus Xtreme shows us the goods with the heat sinks removed!


The VRM is a large 16+2 phase VRM. It uses the IR35201 in 8+0 phase mode, eight IR3599 doublers, and 60A Infineon TDA21462 integrated power stages, which are the latest from Infineon (owns IR too). It's one of the best VRMs we have seen on Z390. The iGPU phases are made up of typical PowerPAK N-channel MOSFETs.


The VCCSA and VCCIO are controlled by Richtek RT8120 single phase PWMs with integrated drivers, and they control some miniature On Semiconductor PowerPAKs labeled "4C06". The memory VRM uses the same Richtek PWMs, but with larger On Semiconductor "4C06N" N-channel PowerPAKs in a two low single high configuration.
