Design Notes

• Rail sequencing order and delay are part of the SoC power-up contract; a wrong order latches the processor even though every rail is in spec.
• In multiphase designs, current balance depends on the loop matching between phases, so keep the layout symmetric.
• Digital interfaces (PMBus, I²C) need pull-ups to the correct rail and a defined state during power-up.
• Thermal design is a system problem here: the PMIC sits next to the load it feeds, so budget the shared copper, not the package alone.
