Mini-Power Management Unit Maximizes Design Flexibility

November 27, 2007 3:47 am | Product Releases | Comments

Advanced Analogic Technologies, Inc. announced the AAT2504, an adjustable 3-channel regulator that combines a step-down converter with two low dropout linear regulators (LDOs). Targeted at mobile devices with rapidly changing feature sets, it allows designers to extend system functionality and still benefit from power management integration. The step-down converter delivers up to 800 mA of output current and supports an input range of 2.7V to 5.5V

Nuclear Bathtub Full of Controversy

November 26, 2007 5:57 am | Blogs | Comments

Productive Product: What if nuclear power were mass-produced in portable battery-like containers? That's the mission of Hyperion Power Generation, a start-up based on the research of Los Alamos National Labs scientist Otis Peterson. The bathtub-sized device with no moving parts could power 25,000 homes for five years, and Hyperion is poised to build 4,000 around

Micro-D Pi Filter Connector for Military, Avionics Applications

November 20, 2007 4:00 am | Product Releases | Comments

ITT Electronic Components developed a Micro-D connector with desirable attenuation. Designated the TMDMP filter, the connector utilizes an internal filter design, providing the density needed to accommodate the ferrite tubes necessary for Pi filtering in military and aerospace applications. The TMDMP filter connector is suitable for integrated avionics and electronic warfare

Power Relays Give Designers Much to Ponder

November 19, 2007 11:52 am | by Jon Titus, Senior Technical Editor | Articles | Comments

My first experience with a relay came about when a friend found a radiosonde -- a small balloon-borne weather instrument -- in the woods behind his house. My friend Ben wanted the parachute, so I got the electronics. As a kid of 11 or 12, the circuitry didn't mean much, but it included a simple relay I experimented with.

Lithium, Ultracaps Merge for Hybrid Power

November 19, 2007 11:13 am | Blogs | Comments

Productive Product: Maxwell Technologies is working with China's Lishen Battery to design hybrid lithium-ultracapacitor products, Maxwell officials said today. Immediately, Lishen will start making lithium cells adjacent to ultracapacitors in the same package, while preparing to merge lithium with ultracapacitors in individual hybrid cells by summer 2009.

High-Frequency Crystal Oscillators Provide Low-Jitter Performance for Communication Applications

November 19, 2007 10:35 am | Product Releases | Comments

Maxim Integrated Products introduced the DS4-XO series of crystal oscillators that support frequency operation from 75 MHz to 622.08 MHz. These miniature crystal oscillators are available in a 5 mm x 3.2 mm package and provide jitter performance of less than 1 psRMS (12 kHz to 20 MHz) over the -40°C to +85°C extended temperature range. Manufactured using fundamental AT-cut crystal technology with no overtone,

VCO for Digital Radio Equipment

November 19, 2007 4:05 am | Product Releases | Comments

Crystek's CVCO55CC-2778-2945 VCO operates from 2778 MHz to 2945 MHz with a control voltage range of 0.1V to 16V. This VCO features a typical phase noise of -110 dBc/Hz @ 10KHz offset and has excellent linearity. It is packaged in the industry standard 0.5" × 0.5" SMD package. Input voltage is 8.0 V,  with a max current consumption of 40 mA. Pulling and Pushing are minimized to 5.00 MHz and 2.00 MHz/V

UCLA Puts Twist on Flexible Batteries

Energy Harvesting in the Military

November 16, 2007 9:18 am | Blogs | Comments

Productive Product: I wrote about energy harvesting a few times before, and now there's a practical application: power for field soldiers. The Seattle Post-Intelligencer reported on M2E Power, a Boise, Idaho start-up that says it has a (no pun intended) more efficient way to perform energy harvesting -- the general idea of energy harvesting from mechanical movements traditionally does work but hasn't been worth the trouble.

Transmission Line Pulse (TLP) is an Effective Analysis Tool for ESD

November 15, 2007 7:26 am | by Robert Ashton, Ph.D., ON Semiconductor | Articles | Comments

Electrostatic discharge (ESD) occurs when objects -- including people, furniture, machines, integrated circuits or electrical cables -- become charged and discharged. Electrostatic charging brings objects to surprisingly high potentials of many thousands of volts in ordinary home or office environments. ESD produces currents which can have rise times less than a nanosecond, peak currents of dozens of Amps and durations that can last from tens to hundreds of nanoseconds. Unless ESD robustness is included during design, these current levels can damage electrical components and upset or damage electrical systems from cell phones to computers.

ATCA: It's More Than a Bus

November 15, 2007 6:45 am | by John Titus, Senior Technical Editor | Articles | Comments

Competitive telecom businesses have realized they can no longer design proprietary hardware. In response to this changed business climate, members of the PICMG, a consortium of industrial-computer vendors, developed PICMG 3.0, or the Advanced Telecom Computing Architecture (ATCA). Marc LeClaire, a product manager in the Advanced Blades and Servers Division at Kontron, stressed that the ATCA standard covers boards, enclosures, interconnections, communications, and other architectural components. "Designers must think of the ATCA as a complete architecture, not simply as a bus."
