Step-Down DC/DC Converter

Linear Technology (Milpitas, CA) has announced the LT3743, a synchronous step-down DC/DC converter designed to deliver constant current to drive high current LEDs. The device’s 5.5V to 36V input voltage range makes it suitable for applications including industrial, DLP projection, and architectural lighting. It provides up to 20A of continuous LED current from a nominal 12V input, delivering in excess of 80 watts. In pulsed LED applications, it can deliver up to 40A of LED current or 160 watts from a 12V input. Efficiencies as high as 95% eliminate need for external heat sinking and simplify the thermal design. A frequency adjust pin enables the user to program the frequency between 100kHz and 1MHz. Combined with a 4mm x 5mm QFN or thermally enhanced TSSOP-28 package, the LT3743 offers a compact LED driver solution and offers both PWM and CTRL_SELECT dimming, offering 3,000:1 dimming capability at three LED current levels.

Precision Linear Motor Stages

Dover, A Danaher Motion Company (Salem, NH), has introduced the MMG Mini-Mag line of precision linear motor stages. Four models are available that deliver 25mm, 50mm, 100mm, and 150mm travel, respectively. They provide uncompensated accuracy ranging from 2um to 8um and resolution ranging from 1.0um to 5nm. Each model delivers repeatability to ±0.4um and is rated for 8kg load capacity. One of the most significant features is an Integral anti-creep linear guideway, which can increase uptime by as much as 15% in high-duty-cycle applications by eliminating the need for homing moves typically required to reset standard crossed roller bearing retainer cages.

Polygonal Laser Scanner

Lincoln Laser Company (Phoenix, AZ) has introduced the KW Series polygonal laser scanner for material processing applications. The scanner uses a solid copper polygonal mirror that rotates to allow the laser beam to transfer rapidly from facet to facet, minimizing dwell time. It can handle beam power densities of 1,000 watts per square millimeter and can achieve active scan angles of greater than 120 degrees or scan rates of over 10 KHz, depending on the mirror/motor combination. The copper substrate acts as a large heat sink, drawing heat away from the mirror facets.

Laser Diode ESD Protection

Pangolin Laser Systems (Orlando, FL) has introduced the L44 Series LASORB™ to protect laser diodes, photodiodes, and LEDs from single, multiple, and repeated ESD events of either positive or negative polarity. It also protects against reverse bias conditions. The LASORB mounts in a 2-pin, through-hole configuration, and features 200-mil pin spacing and a compact (8.9mm × 10.4mm × 3.8mm) package.

Adhesives and Sealants Literature

Henkel Corp. (Rocky Hill, CT) has introduced a six-page brochure of information about Loctite® adhesives and sealants for manufacturing photovoltaic and concentrating solar modules. The literature offers technical data on products for elastomeric bonding and sealing, rigid metal bonding, and junction box potting. The seven Loctite products highlighted for elastic bonding provide high resiliency, high elongation, and good adhesion. For rigid metal bonding, the literature offers data on six structural adhesives formulated to provide durable, strong bonds for frame construction and metal bracket assembly.

Source Code Analysis Tool

AdaCore (New York, NY) has released CodePeer, a source code analysis tool that detects run-time and logic errors in Ada programs. Serving as an efficient code reviewer, CodePeer identifies constructs that are likely
to lead to run-time errors such as buffer overflows, and it flags legal but suspect code typical of logic errors. CodePeer also produces a detailed analysis of each subprogram, including pre- and postconditions, making it easier to find potential bugs and vulnerabilities early. If the implicit specification deduced by CodePeer does not match the component’s requirements, a reviewer is alerted immediately to a likely logic error.

Fanless Industrial Panel PC

The IPPC-8151S from Advantech (Cincinnati, OH) is a 15" XGA TFT LCD fanless industrial panel PC that features
an Intel Celeron®M 1GHz CPU. It includes a tapered and food-safe rubber seal between the bezel and the chemical-resistant touch screen, and an optional fully sealed 316L stainless steel enclosure to satisfy the standards required in food processing, clinical, chemical, or pharmaceutical applications. For waterproof and dust-proof protection, the standard model supports IP66 grade protection on the front panel only, while an optional stainless steel enclosure kit and IP66 I/O module are available to support a fully enclosed IP66 protection for all sides, including I/O ports. The system includes a 1MB L2 cache, 1GB DDR2 memory, a CompactFlash slot, one PCI expansion, and one SATA HDD.
