AnalogicTech has introduced two mini-Power Management Units (PMUs) that combine three step-down DC/DC converters in a single monolithic IC. Targeted at portable devices with rapidly evolving feature sets, the 3-channel AAT2784 and AAT2785 allow designers to add one 1.5A synchronous step-down converter and two 300mA synchronous step-down converters or one 1.5A synchronous step-down converter and two 600mA synchronous step-down converters respectively, without radically altering their existing core system design or adding numerous discrete devices.

Oftentimes portable system designers want to expand the feature set of an existing handset, portable media player or other system, but don’t have the lead time to redesign the system PMU and still meet a rapidly closing market window. By offering designers three independently-controlled switching regulators sized to power a processor core, an I/O and a DSP, ASIC or RF circuitry in a single compact package, the AAT2784 and AAT2785 combine the advantages of functional integration, including simpler component selection, reduced BOM, minimised PCB requirements and shorter time-to-market, with the flexibility and electrical performance of a discrete approach.

Designed for portable applications, the AAT2784 and AAT2785 operate off an input voltage range of 2.7 to 5.5V. Outputs are adjustable from 0.6V to VIN. Both devices employ a unique low noise architecture that reduces output ripple by 25% and spectral noise by up to 50%.

With efficiency levels exceeding 95%, the new devices help reduce power consumption and extend battery life. Quiescent current is a low 50microA per channel. Transient response time is typically < 20micro seconds.

Each of the three regulators in the AAT2784 and AAT2785 has an independent enable pin. A high 1.8MHz switching frequency helps minimise the size of external components and reduce PCB footprint.

An integrated internal soft start function limits current surge at the input and eliminates output voltage overshoot. Both devices also feature over-temperature and current-limit protection.

A company in Brazil that hosts multiuser online gaming is the customer for that hybrid system. Porell said IBM is researching the possibility of creating tools to let a broad set of users run applications across its zSeries and the Cell CPU. The Cell could be used to accelerate functions such as some forms of database analysis using local procedure calls and shared memory pools.

Each z10 mainframe can be sliced up into as many as 60 logical and secure partitions. Hundreds of jobs can be hosted on each partition using IBM's virtualization tools, said Porell.

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX13410E and MAX13415E half-duplex, RS-485/RS-422 transceivers with an integrated low-dropout (LDO) regulator.

The MAX13410E and MAX13415E half-duplex, RS-485/RS-422 transceivers use Maxim's proprietary AutoDirection control architecture to automatically enable the driver when transmitting data. AutoDirection control eliminates the need for a driver-enable control signal, as well as the optocouplers typically required for control-line isolation. To further save space and reduce cost, the integrated LDO regulator features a wide, +6V to +28V supply range, eliminating the need to regulate isolated power supplies. The MAX13410E and MAX13415E are well-suited for isolated-metering, automotive, and industrial applications.

The transceivers offer ±15kV ESD protection (Human Body Model) and thermal-shutdown protection. Additionally, they feature a 1/4-unit load-receiver input impedance, allowing up to 128 transceivers on the bus.


Portland, Ore. — VeriWave, Inc. has expanded its wireless LAN (WLAN) performance testing and analysis portfolio by delivering what it claims is the first 802.11n debugging, troubleshooting and unit test tool to address the early development stages of 802.11 -compliant devices. The WaveDynamix test tool offers developers visibility into how new 802.11 devices will perform in live installations, early in the development cycle, and enables them to reduce the time to test for functional, integration, and field failure test cases.
