The Z390 Aorus Master shows us the goods with the heat sinks removed!
The VRM is a large 12+2 phase VRM with the CPU and iGPU power rails using IR35201 PWM controller in 6+2 phase mode. The 12 phases are doubled up by IR3599, and each of those phases is an IR3553 40A PowIRstage.
The iGPU phases are made up of typical PowerPAK N-channel MOSFETs. The VRM here is smarter and will run cooler than that found on other GIGABYTE Z390 motherboards (except the Xtreme).
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.
