Industry View -- Exclusive to Electronic Design UPDATE ********************** Power And Analog Make Successful Consumer Electronics By Julian Hayes, Vice President of Marketing, Wolfson Microelectronics plc Conventional wisdom in consumer electronics, driven by Moore's Law, calls for increasing functionality on single systems-on-a-chip (SoCs). But the laws of physics (heat, current leakage, crosstalk, etc.) have all but eliminated Moore's Law as a gating factor for functional integration in consumer electronics. Modern microprocessors drain batteries like the engine of a Hummer drains a gas tank, while mixed-signal circuits stubbornly refuse to yield to microscopic digital design rules. Moore's Law was fine for PCs that crunched masses of data and forced users to adapt to unnatural user interfaces like monitors and keyboards. But it doesn't work when terabytes of data, much of it audio, are constantly flowing back and forth wirelessly on a handheld device. However, integration is still a consumer demand. So what's a digital designer to do? Don't worry. It's the analog designer's problem...

Focus On Power ********************** ***Mini Battery Chargers Power Up Portables Two ultra-small battery chargers are designed for consumer-electronics applications such as personal media devices and mobile phones. The SC805 and SC806 charge lithium-ion or lithium-polymer batteries. They come in 3- by 3-mm, thermally optimized Meridian lossless packing (MLP) packages. Both chargers produce up to 1 A when operating in continuous charge mode. During high-power-dissipation periods, they behave like pulse chargers that regulate the internal die temperature to a safe level. An input-voltage range of 3 to 6 V allows for seamless charging from a current-limited adapter. This ensures that the power dissipation for high-output-current designs can occur in a less sensitive wall-plug adapter rather than in the system's internal charging circuitry. The chargers are designed with three programmable charge states: a trickle-charge phase for deeply discharged batteries, a fast-charge phase, and a constant-voltage phase. Available immediately, the SC805 and SC806 battery chargers cost $1.05 and $1.01 each in 10,000-piece lots. Semtech Corp. ==> http://nls.planetee.com/t?ctl=F5F7:1001CD ********************** 3. News -- From The Editors ********************** ***Tools Inch Toward Universal Applications Goal Dissimilar mobile devices and operating systems can make designing software for heterogeneous networks a nightmare. But there's good news. The dream of creating global software applications is a little closer to reality with a set of tools developed by the Design Environments for Global Applications (DEGAS) project. The goal is for the tools to create one set of content and software that can be used on any device or operating system. Funded by the Information Society Technologies (IST) program, the DEGAS project initially defined the key elements of a software program that are common to all devices, such as security, and then separated out any device-specific functions. The project developed a theory to handle heterogeneous networks and produced a set of tools to write software for use on a broad range of devices. Specifically, the researchers developed a mobile adventure game and a mobile commerce solution. The results were so successful that project partner Motorola immediately began commercial deployment of the mobile e-commerce software, which works on a wide variety of handsets. The team used a standard protocol called Universal Modeling Language (UML) to design the key elements of the game and e-commerce software. Design Environments for Global Applications (DEGAS) ==> http://nls.planetee.com/t?ctl=12C0A:1001CD ***DC-DC Converters Deliver Green Power There's no need to worry about lead with the TEN-5WI series of dc-dc converters, which deliver 6 W of output power and fully comply with the RoHS Directive. The 4:1 voltage-input ranges permit operation from a wide array of battery and dc power systems. Fourteen models offer output voltages of 3.3, 5.0, 12, 15, +/-5, +/-12, and +/-15 V dc. They feature 1500-V I/O-isolation as well as short circuit and overvoltage protection. A built-in electromagnetic-interference filter helps the part meet emission standards without need of external components. Operating temperature ranges from -40 deg.C to 85 deg.C. The converters are housed in a DIL-24 metal package with an industry-standard footprint. Mean time between failure (MTBF) ratings are more than 1 million hours, and each part comes with a three-year warranty. Standard pricing is as low as $19.90 in 500-piece quantities.

TracoPower ==> http://nls.planetee.com/t?ctl=12C0C:1001CD ***Online Tool Helps Evaluate Op Amps An online tool from Analog Devices eases the sometimes tedious hand calculations and guesswork involved in the selection and evaluation of op amps. By using parametric data to mathematically model behavior, the tool lets designers select one of the company's voltage feedback op amps, configure a circuit, apply a signal, and then evaluate the amplifier's general performance. The tool examines bandwidth limitations, I/O range, gain errors, and dc errors to ensure that the device is safely and reliably operating within its optimal performance range. Interactive message flags issue a series of warnings if a circuit configuration may lead to amplifier damage or if the circuit yields degraded performance. National Instruments' LabView software powers the op-amp evaluation tool. It's free, it's accessible in real time on the Analog Devices Web site, and it requires no software download.

Electronic Design Helpline ********************** ***Variable Signal Generator Electronic Design reader Andrew Frith asks: "Does anyone know of, or how to make, a signal generator (of sorts) that can produce a square wave output, variable from about 100 Hz all the way up to 50 kHz, and be able to do so in 1- or 2-Hz jumps? Needs to be really stable (obvously), and should have an output of about 200 mA. I'll be running it from a 12-V battery. And the ability to switch from square to sine would be sweet too."
