Fatal1ty H370 Performance Circuit Analysis
The Fatal1ty H370 Performance shows some secrets when we remove the heat sinks.
The VRM is in an 8+2 phase configuration. It uses a UPI Semiconductor uP9521P which offers at least 6 or maybe 8 PWM channels. The CPU phases are controlled by uP1961 doubler with integrated drivers and output to SinoPower SM4337 (high-side) and Sinopower SM4336 (low-side), each phase gets one of each. The iGPU phases use uP1962 single phase drivers and use two low-side MOSFETs per phase. The VCCSA and VCCIO get their own phases made up of the same MOSFETs.
The memory VRM is made up of a single phase PWM controller from Richtek and two low-side MOSFETs The memory VRM uses the same MOSFETs but in a two-phase configuration.
