PMIC FOR MOBILE PLATFORMS SUPPORTING BOTH INTEL
COMMUNICATION PROCESSORS AND INTEL® PXA27X FAMILY
Dialog Semiconductor’s DA9030 is a highly
integrated power management IC (PMIC)
designed to minimize power consumption in
entry-level, mid-range and premium
smartphones as well as personal digital
assistants (PDAs) and communicators with
highly sophisticated multimedia and internet
capabilities. It is targeted at cell phones
incorporating radios for W-CDMA, quad-band
GSM, Wi-Fi (802.11b wireless LAN) and
Bluetooth. The DA9030 manages the complete
power management requirements of both the
communications processor, such as Intel’s
Hermon, and the Intel® PXA27x family of
applications processors in the mobile handset.
Developed in collaboration with Intel, the
DA9030 supports the Wireless Intel
SpeedStep® technology. Combined with
dynamic voltage management (DVM) and
Dialog Semiconductor’s patented Smart
Mirror™ LDOs – which offer very low quiescent
current consumption and high power supply
rejection performance – it enables significant
power consumption and system cost savings
compared to equivalent discrete solutions.
This combination provides intelligent
management of voltage and frequency
changes, optimizing both switching and linear
regulators for maximum power efficiency.
It connects directly to the battery and provides
stable, low noise supplies for all core circuits
within the product. All the supplies are fed
using high performance low dropout (LDO)
voltage regulators using Dialog’s Smart
Mirror™ technology.
A state machine in the DA9030 controls
complete system start up and shutdown
sequencing. Dedicated system level power
management supports the RUN, TURBO, IDLE,
SLEEP and DEEP SLEEP operating states of
the PXA27x processor.
Two high efficiency DC-DC buck converters
provide high current, low voltage supplies to the
main communication processor and additional
memory. Synchronous and asynchronous
modes ensure a high operating efficiency over
a wide range of current demands. One
converter has DVM with programmable voltage
and slew rate control to support the Wireless
Intel SpeedStep® technology and optimize
current consumption of the PXA27x processor.
The DA9030 includes a multimode battery
charger for Lithium chemistry battery packs.
The charger is fully programmable, uses dual
loop monitoring and control for rapid and safe
operation, provide automatic charger detection
and battery pack temperature monitoring. Other
functions integrated include programmable
white LED, general purpose LED, 0.5 Watt
handsfree speaker driver and vibrator driver,
minimizing the need for external components.
