PMIC eliminates power overhead, supports portable device families

Easy setup through a GUI to configure power sequencing and multiple sleep modes

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 overhead 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.

Dynamic voltage scaling can be implemented for five outputs, and dynamic biasing can be used on all linear regulators. Power dissipation is autonomously regulated on-chip. A dual-input switching dc/USB battery charger allows up to 1.2 A to be drawn from a lithium battery with minimal thermal impact to the PMIC. The device is supplied in a dual-row QFN86 7 x 7–mm package with 0.5–mm pitch. (From $3.80 ea/1,000 — available now.)
