New power management IC targets multimedia
applications on PDAs and wireless handsets

Kirchheim/Teck-Nabern, September 29, 2003 – Dialog Semiconductor Plc (NASDAQ: DLGS, Prime Standard: DLG), has announced the DA9031, a new advanced power management controller IC designed to support high performance multimedia applications in high-end personal digital assistants (PDAs) and wireless handsets based on the upcoming processor for portable computing platforms by Intel Corporation, code-named Bulverde.

The new DA9031 is a highly-integrated, complete, single-chip power management controller IC connecting directly to the battery and designed for the growing market of PDAs and wireless handsets capable of capturing and transmitting high quality digital still pictures and video clips. Based on Dialog’s proven mixed signal, low power CMOS technology, key features that make the new controller ideal for such applications are:

- a high-efficiency DC-DC buck converter supporting Intel® Dynamic Voltage Management (Intel® DVM); this is important in adjusting the supply voltage according to processor operating frequency, enabling power consumption to be optimized according to the application being run

- programmable white LED drivers with 20V boost converter to drive two channels of four LEDs very efficiently; this is an important feature for screen and keyboard backlights in the PDA and wireless handset

- a 500mW 8 Ω loudspeaker driver with volume and anti-pop control, for driving multimedia and other audio applications.

The chip provides stable, low noise power supplies for all the core circuits within the PDA or handset, with its additional features including 13 high performance low dropout programmable voltage regulators using Dialog’s
patented Smart Mirror™ technology; RTC (real-time clock) supply; boost converters for SIM card, USB interface and vibrator drivers. The DA9031 includes a programmable multimode battery charger for single cell, 4.2V lithium chemistry battery packs, and supports charging currents up to 1.4A.

Automatic charger detection and battery pack temperature monitoring are also included within this section of the device.

Smart Mirror is a technique allowing the bias of a regulator to be reduced automatically as demand falls and gives dynamic quiescent current control – enabling high PSRR (power supply rejection ratio) and dynamic performance over a wide range of operating currents, without being constrained by the usual design compromise of being over-biased under all conditions except when under maximum load. Overall, this means that designers can extend standby and operating times without requiring additional software to control low power modes or needing complex PCB design with hard wired low power select lines.

Samples of the DA9031 will be available in the fourth quarter of 2003, with the device incorporated in a 196-pin BGA, 0.5mm pitch package.

Editor’s notes:
1) Dialog Semiconductor and Intel background
The DA9031 power management IC for PDAs and cellphones is the result of a development and marketing initiative between Dialog Semiconductor and Intel to support existing and future Intel® Personal Internet Client architecture (Intel® PCA) system level products. The first product to be launched by Dialog as part of this
initiative was the DA9010 highly integrated audio and power management solution for the Intel® PXA800F Cellular Processor. The DA9010 was launched in February 2003, and provides on a single chip the key power management and high performance audio functions for a GSM/GPRS cellular phone handset.

2) PDA market According to high-tech market research firm In-Stat/MDR, the PDA market will reach over 11 million units this year and will grow to just under 25 million units in 2007. Manufacturers are realizing the market opportunities from convincing consumers that PDAs can be more than just PC peripherals, and the newest devices will incorporate new features that emphasize their multimedia and wireless capabilities, including the ability to receive content from a camcorder, integrated GPS, and higher megapixel cameras with flash and zoom functionality.

3) Camera phone market
Shipments of handsets with an integrated digital camera will show a compound annual growth rate of 53.2% through 2007, according to In-Stat/MDR. New handsets will be " smart" in a variety of ways, and a built-in camera will be standard. In 2002, camera phone shipments equated to 18.2 million units, and in Q1 2003 this figure was 7.8 million units.

O.K., wenn ihr nicht kaufen wollt, dann leg halt ich nochmal nach. Hier kann man nicht viel falsch machen - und die Amis werden die Nachricht wohl doch etwas mehr zu würdigen wissen...
Freu mich schon auf die USA-Eröffnung...

Klingt gut, bin leider bereits vollinvestiert, auch in dlg
