Camden Electronics has published a new catalogue for 2007 detailing the company's wide range of components for electronics, telecommunications, lighting and security applications.

There has been a lot of TV coverage recently concerning the Dallas Cowboys giant video displays at their new stadium in Arlington. The $40m, four-sided, high-definition Diamond Vision video board, which is built by Mitsubishi Electric, uses 22,000 TDK-Lambda ZWS power supplies to light the 25 million Light Emitting Diodes (LEDs) needed to create the image on the screen.

New from Allegro MicroSystems Europe is the A6285, a 16-channel constant-current LED driver featuring individual channel current adjustment via a 7-bit dot correction register. Each channel of the A6285 can sink a constant current up to 80 mA, and a single external resistor sets the maximum LED drive current for all channels. Each channel's drive current can be individually adjusted from 0 to 100% of the maximum value via the dot correction regi...

At Infrarail 2008, the HARTING Technology Group is featuring a broad range of interconnection solutions for the modern rail industry, including connectors for power and signal transmission as well as industrial Ethernet components to support new networking technologies.

The Yokogawa AQ6373 is an optical spectrum analyser designed to carry out measurements over the wavelength range from 350 to 1200 nm, including the visible light spectrum from 380 to 780 nm. In addition to its world-class optical performance in areas such as resolution, accuracy, sensitivity, measurement speed and dynamic range, the AQ6373 features a colour analysis function which makes it ideally suited to measurements on LEDs and laser light s...

Catalyst Semiconductor has announced the CAT4004, a new four-channel LDD (low dropout driver) designed for emerging, power-conscious portables where the LEDs are driven directly from the battery. With the migration of white LEDs to lower forward voltages, a number of portable applications are now able to drive LEDs directly from the system battery without the need to boost voltage. The new CAT4004 is designed specifically to meet the needs of t...

Catalyst Semiconductor has announced a 2W LED driver to address high-power backlighting applications. The CAT4240 boost converter provides a high switch current up to 750mA and high voltage up to 38V, making it ideal for driving a wide range of backlighting applications ranging from 1W LEDs in series to multiple strings of lower-power LEDs.

USB silicon and software specialist Future Devices Technology International Limited (FTDI) announced Vinculo, an embedded development platform inspired by the popular Arduino Duemilanove / Uno. The Vinculo platform allows designers to integrate powerful USB 2.0 interfacing by incorporating FTDI’s Vinculum II VNC2-64 dual-channel USB Host/Slave controller with the capability of interfacing to the growing range of I/O application boards (shields...

Linear Technology announces the LT3597, a 60V, 1MHz, step-down DC/DC converter designed to operate as a three channel, constant current LED driver. Each channel of the LT3597 contains a constant current sink LED driver with a dedicated adaptive-output buck converter.

Linear Technology has announced the LT3595, a 45V 2MHz DC/DC buck mode converter designed to operate as a 16-channel constant current LED driver. Each channel of the LT3595 can drive up to ten 50mA LEDs in series, enabling the LT3595 to drive up to 160 50mA LEDs while delivering efficiencies up to 92%. Its multichannel capability makes it ideal for large TFT-LCD backlighting applications. Each of the 16 channels is independently operated and can ...
