Diodes has introduced a family of LED driver ICs capable of significantly reducing the number and size of external components required by drive circuits. The AP880X step-down dc-dc converters need the support of just four components and by operating at switching frequencies up to 600kHz, enable the use of smaller and lower cost inductors and capacitors.

Marl International was named Business of the Year at the Westmorland Gazette Business and Tourism Awards, fighting off competition from companies across South Cumbria, North Lancashire and the Dales. Marl was also presented with The Westmorland Gazette’s Innovation and Technology Award.

Learn about alternate solutions for driving LEDs. Watch a demonstration of a T8 fluorescent tube light replacement comparing a common switching regulator based solution and a Constant Current Regulator (CCR) biased solution for driving LEDs. See the benefits of using CCR's for driving LED applications.

ON Semiconductor has launched two new GreenPoint reference designs that will speed and simplify the development of high-efficiency LED-based lighting applications.

ON Semiconductor has introduced a series of two-terminal linear constant current regulators ideal for driving current in automotive, industrial signage and architectural LED lighting applications. The new constant current regulators operate over a wide range of input voltages and provide engineers a simple and cost-effective solution for regulating current in their applications without compromising on performance.

Murata Power Solutions has introduced three new PICMG 2.11 compliant CompactPCITM high reliability power supplies. The cPCI-A-3U-300C, cPCI-A-3U 200C AC/DC power supplies and the cPCI-D-3U-300C DC/DC power supply are all housed in industry standard 3Ux8HP enclosures and are capable of delivering continuous full power across their -5ºC to +55ºC operating temperature range with airflows as low as 250lfm. All three models have efficiency levels i...

Freescale Semiconductor has introduced the MC34845 LED driver with high-speed pulse width modulation (PWM) capability. This six-channel device is designed to allow LED backlights to operate at frequencies above the audible range, thereby eliminating noise issues and reducing visual artifacts. In addition, the driver’s accuracy and flexibility offer display uniformity and a wide dimming range to further enhance end-user experiences.

Semtech today announced the industry’s first smart current sink LED backlighting platform with on-chip digital lighting effects for high-end handheld displays.

Semtech announced the newest devices in its sub-1 V mixed-signal LED and motor timer-controller platform for easy, fast and cost-effective design of small, light weight, ultra-low power, battery-operated electronic appliances. The new SX8120 and SX8121 devices operate intrinsically at 0.9 V to control a DC motor or other continuous low-voltage element and drive a high-brightness LED directly from a single battery. Because they operate inherently...

Following the ratification of the IEEE802.3at standard for Power-over-Ethernet applications up to 25.5 watts, Phihong continues to offer the broadest range of .at-compliant midspans. Providing up to 30W per port and in full compliance with the final power specifications released earlier this month, Phihong's PoE Plus midspans are available in single-, 4-, 8- and 16-port models. Applications that will benefit from the increased IEEE802.3at power l...
