The DA9030 is a highly integrated system level power management IC (PMIC) which in one device supports both a communications processor and the new Intel PXA27x family of applications processors in next generation mobile handset designs. The DA9031 variant of this PMIC, launched last year, has also now been updated to support stand-alone Intel PXA27x processor-based applications such as PDAs and handheld multimedia devices.
Key benefits of the DA9030 PMIC are minimised power consumption in entry-level, mid-range and premium smartphones, personal digital assistants (PDAs) and communicators with highly sophisticated multimedia and Internet capabilities.
Targeted at a new generation of cell phones incorporating three radios for W-CDMA, quad-band GSM, Wi-Fi (802.11b wireless LAN) and Bluetooth, it manages the complete power management requirements of both the communications processor and the applications processor, including full system start up and shut down.
The new DA9030 PMIC is the first to support the Wireless Intel SpeedStep technology, which when combined with dynamic voltage management (DVM) and Dialog's patented Smart Mirror LDOs (low-dropout regulators) produces significant power consumption and system cost savings compared to equivalent discrete solutions.
The combination of technologies provides intelligent management of voltage and frequency changes, optimising both switching and linear regulators for maximum power efficiency in the system.
The PMIC is the only device to contain 19 high-performance voltage regulators, two high-efficiency buck convertors with programmable output voltages, five individually selectable LED drivers, programmable battery charger, audio drivers, and many more other functions in a single highly integrated CMOS chip.

Developed in close co-operation with Intel to achieve the most optimised PMIC for mobile handsets, operation of the DA9030 is functionally verified in the Intel PXA270 development kit as well as the Intel PXA270 phone reference platform.
The PMIC connects directly to the phone's battery and provides stable low noise power supplies for all the core circuits within the phone as well as additional regulators for many other features - such as camera modules, LCD display, Bluetooth, and memory cards.
Special modes supported include "PDA", where the communications processor subsystem is in standby mode, but the user still needs to operate functions such as MP3 music playback, video playback and games on the applications processor.
Roland Pudelko CEO and president of Dialog Semiconductor said: "We have combined our expertise in advanced mixed signal design for mobile phone handsets and our system-on-chip integration capability for high and low voltage circuits to produce a very advanced power management device containing 38 different types of functional blocks on a small die size in a 0.25 micron CMOS process".
"This has resulted in a very sophisticated IC that allows mobile phone users to maintain the long standby times they have been used to with previous generation handsets, despite the extra demands made on the battery".
"Intel's vision is to enable new possibilities through handheld, wireless connectivity, but improving the user experience and adding additional multimedia functionality cannot come at the expense of reduced standby time", added Mark Johnston, Director of Marketing for Intel's Cellular and Handheld Group.
"Dialog Semiconductor's experience in delivering power management ICs that are optimised to work with Intel XScale technology-based platforms meets that demand by supporting Wireless Intel SpeedStep technology for longer battery life in wireless clients".
The DA9030 is available now and an applications development platform comprising application board and software allows users to quickly verify the device in their target application with full access to all device functionality and debugging access to the power management I2C bus.
