The board routes the primary power lines directly from the battery and USB-C sub-board through a highly resilient Board-to-Board (B2B) connector. The PMI632 regulates the input to establish the system's main power rail, known dynamically as VPH_PWR . This rail sits roughly between depending on current load and battery state. Core Power Rails (PM439) The PM439 breaks VPH_PWR down into tailored voltage rails:
