ASRock Fatal1ty Z370 Gaming-ITX/ac Motherboard Review
Circuit Analysis
The Fatal1ty Z370 Gaming-ITX/ac hides the goods under the heat sink.
The VRM on this motherboard uses Intersil's new digital PWM, the ISL69128, and new Smart Power Stages, the ISL99227. The VRM is in a 5+2 phase configuration for the CPU VCore and iGPU. The CPU VRM is in an 8+2 phase configuration for the CPU core and iGPU. The power stages are rated for 60A, as are the inductors, and the capacitors are rated 12K.
The new PWM controller supports up to 7 phases in two rails, and the power stages report back stats to the digital PWM. Some Maxim Semiconductor PWMs are used to supply more minor rails such as VCCSA and VCCIO.
The memory VRM consists of a Fairchild Semiconductor FDPC5030SG dual N-channel MOSFET, which is similar to the 15A/25A NexFETs. It's controlled by a Richtek RT8231, which is a complete DDR4 memory power supply controller. It controls main DDR voltage, DDR VPP, and VTT.
