Vishay is broadening its optoelectronics portfolio with the release of two high-speed analog optocouplers in the industry-standard SOP-5 package, saving up to 75 % in PCB space compared to a DIP-8 SMD package. The new VOM452T and VOM453T feature a baud rate of 1 MBd in a low-profile package with a height of 2.0 mm. They also feature a very short propagation delay of 1 µs which is critical for applications requiring faster switching times than s...

NXP today announced the SSL2115x series of high-efficiency GreenChip driver ICs for low-cost LED retrofit lamps. The new SSL21151 and SSL21153 are designed for non-dimmable 5W and 10W LED lamps respectively, providing good current control in flyback and buck-boost configurations. The SSL2115x enables small form-factor LED drivers, using primary-side sensing to regulate current, and offering integrated LED open/short protections, an internal 700V ...

OMC can now offer bespoke backlights for LCDs based on a new emitter design that provides the brightness of a dual chip emitter but requires only the forward voltage of single chip solution. Therefore, for the first time, users can drive OMC’s white and blue Profiled Backlight range from a 5V source, which OMC say is becoming ever more desirable in modern applications.

Marl International has invested £150,000 to double its manufacturing output at its site in Ulverston Cumbria, putting it in a prime position to benefit from the rapid growth of an emerging ‘green’ lighting technology. The line has been specially modified to handle PCB boards of up to 600mm long, much more than the standard length. Such boards are commonly required to replace conventional lighting products. The announcement brings the investm...

Standard LED drivers (buck topology) require the input voltage be higher than the output voltage which can cause problems when working with the newest high power LEDs and powering them from low voltage sources like solar cells or batteries. Buck driver solutions, which must always have a higher input voltage than an output voltage, typically result in a design that requires multiple drivers for multiple led strings with lower forward voltages. Th...

TouchNetix today announced the first product in their Brilliance series of projected capacitive touchscreen modules. The TNxBR-104A001 is a complete 10.4 inch multi-touch module comprising a 2 mm chemically strengthened and abrasion resistant front glass, ITO on PET sensor, PCB flex tail for connectivity and a driver IC. Designed specifically for use in mission critical and high performance applications where conducted EMC is often high, the modu...

NXP Semiconductors N.V today announced the availability of several new LED driver ICs in its SSL2108x family for compact, non-dimmable retrofit lamps, following the success of the SSL21081. With the addition of the SSL21082, SSL21083 and SSL21084, NXP now provides a single platform for lamp designers developing for 100V – 120V and 230V mains voltages, as well as all power ranges up to 25 W. Based on GreenChip™ technology, the SSL2108x family ...

ELECTRONIC ASSEMBLY has added the EA DOGM128-6 model to its EA DOGM product family. The seven different optional LED backlights can be combined with five different available display technologies to give some 20 different configurations. With its superflat design and extraordinarily low energy requirement, the DOGM128-6 is particularly ideal for use in battery-operated mobile devices. An optional touch panel allows the implementation of interactiv...

As LED lighting continues to grow in popularity, especially in residential lighting applications, designers are looking for efficient dimming solutions – when compared to TRIAC methods – that also fit within existing sockets. Additionally, these solutions need to work reliably in a small space while providing high efficiency. To help designers meet this challenge, Fairchild Semiconductor has developed the FL7701 Smart Non-isolated Buck LED dr...

Densitron’s new Character OLED modules provide a cost-saving and mechanically compatible solution to Vacuum Fluorescent Display (VFD) users who are looking for a replacement/upgrade option that offers greater value. Compared to VFDs, OLED displays have faster response time and wider viewing angle (near 170°), as well as higher contrast (10000:1), brightness (100 cd/m2) and colour saturation without the need for colour filters. OLED modules of...
