The VRM is in an 4+2 phase configuration and utilizes the Intersil ISL95712 in 4+2 phase mode. It seems that the PWM controller offers two integrated drivers for the main rail and one for the SoC rail, so they added three ISL6625A drivers to facilitate the VRM. Each power stage is in a two-low one-high MOSFET configuration. The low-side MOSFETs are the SM4364A and the high side are SM4377.

The memory VRM is a single phase controlled by the Anpec APW7120 and two SM4377 MOSFETs.
