Registers This deviceisa multi-function programmable Power
Management Unit (PMU), optimized for sub block
• Adjustable Startup Sequence Through Serial power solutions. This device integrates two highly
Interfaceor Configuration efficient 600-mA step-down DC-DC converters
• Thermal Shutdown Protection configurableupto 800-mA load with Dynamic Voltage
Scaling (DVS) via the serial interface, two low-noise
APPLICATIONS analog LDOs, three digital LDOs for upto 300 mA
load current each, two Low-Input Low-Output (LILO)
• Multimedia Processors regulators, and anI2 C-compatible serial interfaceto
• Portable Handheld Products allowa host controller accessto the internal control
registers. The device also features programmable
power-on sequencing. LDO regulators provide high
PSRR and low noise ideally suited for supplying
powerto both analog and digital loads.
The device can be configured either asa Sub_PMU
for modules (for example, camera or multimedia
modules)or asa stand-alone PMU that powers the
processor itself.
