PMIC eliminates power overhead, supports portable device families

摘要

The DA9052 is a platform power management integrated circuit (PMIC) capable of supporting families of application and mobile graphics processors. The device is set up through a GUI to configure power sequencing and multiple sleep modes. Up to 14 power supplies, 16 GPIOs, and other system functions may be adapted in different operating modes to eliminate power consumption over-rnhead in the host processor. The PMIC integrates four dc/dc buck converters and 10 programmable LDOs on-chip. The LDOs can be connected to the dc/dc converters to improve system efficiency. Each output can be connected in series or parallel.
