The Fatal1ty X370 Gaming K4's secrets are revealed once the heat sinks come off.
The VRM on the motherboard is in an 8+4 phase configuration resulting from the doubling of 4+2 phases. The International Rectifier IR35201 offers 8+0, 7+1, and 6+2 PWM channel rail modes, and ASRock is using the 6+2 mode in a 4+2 phase configuration. The tried and true PWM is matched up with three doubler/dual driver IR3598 chips, but they aren't being used as doublers. Rather they are used as dual drivers since the IR3598 can take in two PWM channels and offer two driver outputs.
The CPU Core gets two IR3598, and the SOC rail gets one. The output from each dual driver is connected to two sets of power stage components; this method of doubling just adds an extra set of power stage components. The method used here improves full load performance, but it's that great for light-load efficiency. Anyways, the high and low side MOSFETs are the NIKOS PK618B and PZ0903BK PowerPAKs. They seem to get the job done fine. The motherboard does use 12K polymer solid capacitors.
A single Richtek RT8120D single phase PWM with integrated driver outputs to two phases using the same doubling method as the CPU VRM and the same power stage and output filter components.
