Power Management Unit for Application/Multimedia
Processors and Sub-Systems
General Description
This device is a multi-function, programmable Power Man-
agement 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 Dy-
namic Voltage Scaling (DVS) through an I2C, 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 ac-
cess to the internal control registers. The device also features
programmable power-on sequencing. LDO regulators pro-
vide 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 mod-
ules (for example, camera/multimedia modules) or as a
stand-alone PMU that powers the processor itself.
