MP5472 3-16V, 6A Dual-Output PMIC QFN-26
The MPS MP5472 is a Dual-Output PMIC. It operates from a 3 V to 16 V input, is rated for 6 A and switches at 1.25 MHz. It is supplied in a QFN-26 package.
The MP5472 is a complete power management IC (PMIC) that integrates two high-efficiency, step-down DC/DC converters, one adjustable- output low-dropout (LDO) regulator, and a flexible logic interface.

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.
