LONDON " Dialog Semiconductor Plc has started sampling a tightly integrated system level power management IC that in a single CMOS device supports both a communications processor and the Intel PXA27x family of applications processors.
The part, dubbed the DA9030, is targeted at next-generation mobile handsets and comes with an applications development platform. The DA9031 variant of the power management IC, launched last year, has also been updated to support stand-alone Intel PXA27x processor-based applications such as PDAs and handheld multimedia devices.
The DA9030 is the first to support Intel's Wireless SpeedStep technology, which, when combined with dynamic voltage management and Dialog's patented smart mirror low-dropout regulators, is said to provide significant power consumption and system cost savings compared to equivalent discrete solutions.
The combination offers intelligent management of voltage and frequency changes, optimizing both switching and linear regulators for maximum power efficiency. The chip also contains 19 high-performance voltage regulators, two high-efficiency buck converters with programmable output voltages, five individually selectable LED drivers, programmable battery charger and audio drivers.
The power management chip also connects directly to the phone's battery to provide stable low-noise power supplies for core circuits within the phone as well as additional regulators for features such as camera modules, LCD display, Bluetooth links and memory cards.
