Meet the demand for high-availability power systems at lower power levels Design How-To 5/29/2006 Post a comment Redundant power architectures are found anywhere where the system up-time is required such as large telecom, and datacom, but now, smaller systems are looking to add power supply redundancy as a means of differentiating from competitors. High availability power solutions for relatively low power requirements can now be built and here's how to do it economically with a building-block approach.
50-watt sixteenth-bricks deliver full power at up to +70 C Product News 5/26/2006 Post a comment Power-One's SSQ Series of sixteenth-brick DC/DC converters delivers 50 watts and up to 95 percent of full rated power at +70 C with as little as 200 LFM cooling for intermediate bus architectures, telecom, datacom, wireless communications, and servers and workstations.
Dual-axis servoamp drives a wide range of motors Product News 5/22/2006 Post a comment Copley Controls' Model 800-1514 servo amplifier provides independent (torque) control of two brushless motors. It's compatible with universal encoder and Hall feedback systems and thus frees designers to mix and match motors from different manufacturers.
Get straight on ultracapacitors Power DesignLine Blog 5/19/2006 Post a comment Ultracapacitors have gained recognition for a possible use in many applications but there are still some misconceptions about them. Here's some straight talk to fill you up with the ideas.
8-amp POLs cite power-density edge for distributed-bus apps Product News 5/17/2006 Post a comment Citing a step increase in current delivery and power density over the traditional small-footprint point-of-load converter, FDK's FPMR12TR7508NA (0.9-by-0.4-by-0.195 inch SIP package) and the FPMR12SR7508NA (0.8-by-0.45-by-0.211 inch SMD package) deliver 8 amps for intermediate bus and distributed power applications.
Li-Ion battery chargers -- not just another design Design How-To 5/17/2006 Post a comment You are mobile, therefore you have batteries -- and they need charging. However, reaching the end-of-charge voltage target accurately and smoothly is the key feature of a charger. This article shows how it is done now and what some future possibilities are for Lithium-Ion batteries - to keep you mobile longer.
2-watt POL is economical in tight layouts Product News 5/16/2006 Post a comment BI Technologies' 2-watt point-of-load converter uses a ceramic base and hybrid technology to virtually eliminate any external heat sink requirements, thus reducing the overall installed cost of the device.
All-day batteries, are we there yet? Power DesignLine Blog 5/12/2006 Post a comment There have been several news items in recent weeks about new battery technologies or improvements on existing designs. It seems they all have one thing in common -- they're not here yet.
Digital power monitors cool blade servers Product News 5/10/2006 Post a comment Analog Devices introduces a family of digital power monitors that reduce power requirements, cost and thermal challenges in blade servers, blade PCs and advanced telecom computing architecture (ATCA) cards.
24-port midspan cuts PoE costs in half Product News 5/10/2006 Post a comment Phihong gigabit power-over-Ethernet (PoE) midspan, the POE370U Series for 10-, 100-, and 1000-Base-T networks, touts reduced system cost - barely more than half the cost of competing products.
Half-bridge topology finds applications in high density power converters Design How-To 5/8/2006 1 comment Topologies that had previously been used only in high power applications are now finding their way into medium and lower power applications. However, successful design of a high density power converter requires topology selection as the first and most important choice. Find out how to make the right choices.
Filtronic in talks to sell its PA operations News & Analysis 5/5/2006 Post a comment Shares in wireless communications and compound semiconductor company Filtronic plc rose sharply on the London market Friday (May 5) as the company said it is in negotiations to sell to Powerwave Technologies Inc. the transmit receive module and power amplifier businesses of its Wireless Infrastructure Division.
Europe charges up battery recycling rules News & Analysis 5/3/2006 Post a comment Battery manufacturers and resellers are to be forced to dispose of spent units, especially those used in laptops and mobile phones, and new batteries will be restricted in the amount of mercury and cadmium they can contain, according to a deal agreed by European Union lawmakers as part of a contentious health and safety directive.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
