Semtech - Smart Current Sink LED Backlighting Platform
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 Single-Cell LED and Motor Timer-Controllers Simplify Design of AA/AAA Battery-Operated Electronic Appliances
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...
Phihong PoE midspans meet new specifications, ready for even higher-power applications
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...
MAX8847/48: Backlight drivers with adaptive mode switching boost efficiency by 12% in portable devices
Maxim Integrated Products introduces the MAX8847/MAX8848, negative charge pumps for up to 6 or 7 white LEDs (WLEDs) in a 3mm x 3mm TQFN package. These backlight drivers employ a negative-charge-pump architecture to eliminate in-line resistance from the battery to WLEDs. As a result, mode switching from 1x to 1.5x is delayed during battery discharge, thereby minimizing dropout. The proprietary adaptive-mode-switching technology controls each LED i...
MAX16838: Maxim releases the first two-string HB LED driver for automotive applications
Maxim introduced the MAX16838, the industry's only two-string HB (high-brightness) LED driver for automotive applications. This device integrates a boost or SEPIC switching converter, two linear current sinks, and all necessary power MOSFETs. The MAX16838 is able to optimize conversion efficiency, provide complete fault protection, and allow a 5000:1 dimming range-without any external components. This HB LED driver is well suited for LCD backligh...
Cree Announces Industry’s Most Energy-Efficient Neutral and Warm Lighting-Class LEDs
Cree, Inc announced the commercial availability of the award-winning XLamp XP-G LED in warm- and neutral-white color temperatures (2600 K to 5000 K CCT). These new XP-G LEDs extend Cree’s highest level of light output and efficacy across the white color spectrum, driving general lighting applications such as LED replacement lamps, outdoor area and commercial luminaires.
Europe’s First All-LED Industrial Plant Opens in The Netherlands
The LED lighting revolution achieved another victory with the opening of an industrial plant lit exclusively with LEDs. Located in Etten Leur, The Netherlands, the full-service consumer products packaging plant is owned and operated by Kompak. All interior and exterior lighting fixtures feature Cree XLamp® LEDs and were developed and installed by LedNed, a Dutch LED lighting pioneer.
Cree Extends LED Market Leadership with Industry’s Most Color-Consistent LEDs
Cree is taking another leadership position in the LED industry with the addition of the industry’s smallest warm and neutral bins to its award-winning multichip XLamp MP-L and MC-E EasyWhite LEDs. This breakthrough offers a single two-step MacAdams ellipse bin per color temperature, optimized to achieve incandescent-like color consistency and eliminating the need to purchase multiple small bins and perform complex color mixing.
