Earlier PS4s used 4+1 phase VRMs. The JDM-040 exclusive schematic shows a controller, but phase 5 and 6 are cloned via a secondary gate driver. This means 90% of "APU failure" repairs are actually a dead phase #5 filter capacitor. The schematic gives you the exact part number (SP-Cap 560uF, 2.5V) and its alternate location hidden under the EMI shield.
Because original parts are drying up, repair shops rely on these schematics to board-swap components from donor controllers. The "exclusive" schematic today becomes the "public domain" schematic tomorrow. But currently, the best, most accurate, and most detailed version remains a closely guarded secret among top-tier repair technicians. jdm040 schematic exclusive
