The Z270GTN reveals its VRMs and PCH when the heat sinks are removed.
The VRM on this motherboard for the CPU uses PowerPAK MOSFETs. There are four phases for the CPU Core, two for the iGPU, and another for the VCCSA.
The CPU and iGPU use an Intersil ISL95866 hybrid-digital PWM designed for integrated systems. The PWM offers 4+3 phase operation, Biostar is using it in 4+2 phase mode. The larger rail gets two integrated drivers, while the smaller rail gets a single. The main CPU rail gets two ISL6608 drivers, resulting in a true 4-phase VRM. Sinopower SM4377 and SM4363A MOSFETs are used.
The VCCSA uses an Anpec APW7120 PWM with an integrated driver to drive a single-phase that uses Sinopower SM4377 for both the high-side and low-side MOSFETs. The memory VRM is located below the memory DIMMs and uses a mixture of switching and linear regulation.
