This device is a multi-function programmable Power Management Unit (PMU), optimized for sub block power solutions. This device integrates two highly efficient 600-mA step-down DC-DC converters configurable up to 800-mA load with Dynamic Voltage Scaling (DVS) via the serial interface, two low-noise analog LDOs, three digital LDOs for up to 300 mA load current each, two Low-Input Low-Output (LILO) regulators, and an I2C-compatible serial interface to allow a host controller access to the internal control registers. The device also features programmable power-on sequencing. LDO regulators provide high PSRR and low noise ideally suited for supplying power to both analog and digital loads.
The device can be configured either as a Sub_PMU for modules (for example, camera or multimedia modules) or as a stand-alone PMU that powers the processor itself.
