Power manager looks to next-generation multimedia
The DA9031 is an advanced power management controller IC designed to support high-performance multimedia in high-end PDAs and wireless handsets based on the upcoming Intel Bulverde processor.
The DA9010 audio and power controller is the first product available under 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.
A full GSM/GPRS system solution comprising the new DA9010, together with Dialog's DA35xx series digital camera modules enabling high quality photo imaging and video capabilities, has been verified and recommended for embedded applications using the Intel PXA800F cellular processor.
"Since low power consumption is a key goal, we chose to work with Dialog because of their experience in delivering integrated power and audio management functions to the cellular handset market", said Hans Geyer, Intel vice president and general manager of the PCA Components Group, "Together, our devices significantly reduce the total number of integrated circuits in the mobile phone - making the possibility of smarter handsets with longer battery life even more of a reality today".

Controller manages handset power and audio
Dialog Semiconductor has updated its integrated power management and audio solution for the Intel PXA800F cellular processor.
Roland Pudelko, CEO and President of Dialog Semiconductor added, "Our work with Intel is exciting as they have chosen to utilize Dialog's core competence in audio and power management.
Now, wireless device manufacturers can quickly and cost-effectively introduce products based on the Intel XScale technology and Dialog's proven mixed signal, system level solutions design expertise.
The combination will enable new, powerful innovations in the cellular handset market segment".
The DA9010 represents an industry first, providing a level of integration not seen before in this class of device.
Designed especially for the Intel PXA800F cellular processor, the DA9010 connects directly to the phone's battery, and provides stable low noise power supplies for all circuits within the phone.
Additional regulators are available for enhanced application capabilities such as Bluetooth modules, camera modules, and SD memory cards.
On a single chip, the Dialog controller includes 12 high-performance low dropout (LDO) regulators, high efficiency DC/DC buck convertors, LED and vibrator drivers, 24bit stereo DAC and 16ohm headphone drivers.
A unique feature of the new GSM/GPRS audio and power controller is the Dialog Smart Mirror technology (patent pending).
It enables the Dialog LDOs to use an advanced compensation and biasing technique compared with conventional regulators, by which the regulators are able to bias themselves proportionally to the output current requirement, without needing to switch between different operating modes (such as sleep or normal modes).
This low quiescent current consumption, together with high power supply rejection performance, eliminates the need for a low power mode, simplifying power control design in the phone handset.
In addition to controlling the supplies within the phone, the DA9010 provides a multimode battery charger, supporting 4.1 and 4.2V lithium cells.
The fully programmable charger uses dual loop monitoring and control for rapid and safe operation.
The IC includes automatic charger detection and battery pack temperature monitoring.
On the audio side, the DA9010 enables CD quality sound with its 24bit stereo DAC which uses multibit modulator technology.
An analogue mixer and headphone driver is optimised for driving portable MP3 players and similar equipment.
The DA9010 is available for sampling now as a standard part, in a 121-pin, 8 x 8mm BGA package.
