DA9053 is a quad buck PMIC subsystem with supply domain flexibility to support a wide range of multicore application processors including ARM multicore devices, associated peripherals and user interface functions.

Combined with a switched-mode DC input/USB compatible charger, full power path management and multiple sleep modes, the device offers an energy-optimized solution suitable for portable handheld, wireless and infotainment applications. Interfacing directly to a Li-Ion/Polymer battery pack, the high efficiency switching charger supports precise current/voltage charging as well as precharge and USB modes without processor interaction.
