Integrated PSU chips
join Smartphone concept

Intel Corp has selected the PMU+ single-chip power management unit for its Microsoft Windows Powered Smartphone concept design developed in partnership with Microsoft

Intel Corp has selected the PMU+, Philips' recently introduced single-chip power management unit, for its Microsoft Windows Powered Smartphone concept design developed in partnership with Microsoft. The latest reference design from Intel combines the Intel Personal Internet Client Architecture (Intel PCA) with the Philips PMU+ to allow designers to add features such as colour displays, wireless connectivity and streaming media to Smartphones, while reducing the size, power consumption and end-user cost.

"Philips PMU+ is a highly functional power supply companion for the new generation of smart phones using processors based on Intel XScale technology", said Mark Casey, Director of Marketing for Intel's PCA components group.

"The PMU+'s power management capabilities complement the Intel PXA26x processors to dramatically reduce power consumption in smart phones".

"Power management is a critical factor in mobile devices.

As Microsoft continues to deliver rich functionality in our Windows powered software, we're pleased to have innovative power management solutions from industry leaders like Philips available to our hardware partners", said Andy Haon, Director of the mobile devices Division at Microsoft Corp.

The Philips PMU+ has a unique real-time control feature that can reduce power consumption by up to 70% in smart phones and wireless PDAs.

The control feature allows the handheld device to continuously adjust all the power supplies in the PMU+ to the lowest voltages necessary for the functions being used in that power domain, minimising power consumption and extending battery life.

By continuously adjusting the supply voltages to each power domain (ie the processor, memory subsystem, display backlight, and wireless components), designers can create handheld products that include all the application features a consumer wants, while still using less power than previous models.

"Philips continues to work with industry leaders to provide great products and concept designs for developers of handheld devices", said Dirk Logie, Vice President and General Manager of Power Management for Philips Semiconductors.

"For wireless and PDA applications, Philips power management technology is the clear leader in improving efficiency and dynamically optimising voltage levels to minimise power consumption in a wide range of handheld consumer devices running a variety of mobile applications".

On a single PMU+ chip, Philips integrates a flexible on-chip battery management system, eight programmable power supplies, battery charger, a 10bit ADC, touch screen interface and other features required for wireless handheld devices.

Because of this high level of integration, the chip uses 50% less space and costs 30% less than equivalent semiconductors.

The PCF50606 PMU+ and PCF50605 PMU+ use an HVQFN56 8 x 8 x 0.85mm package.

Engineering samples and evaluation kits for both chips are available now from Philips.
