DURHAM, N.C.--(BUSINESS WIRE)--Cree LED, an SGH company (Nasdaq: SGH), and Current Lighting Solutions, LLC announced that they entered into a patent license agreement, effective October 2022, with ...

This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched two new photorelays "TLP170AM" and "TLP170GM" in a small 4-pin SO6 package, for security systems, ...

This file type includes high-resolution graphics and schematics when applicable. Many applications for LED illumination require wide dimming ratios, which can be easily done using an adjustable ...

Date Announced: 20 Dec 2007 Linear Technology has announced the LT3478 and LT3478-1, two 40V, 4.5A DC/DC converters designed to drive high current LEDs at constant current. Their 2.8V to 36V input ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Under the agreement, Cree LED has been granted by Current, a limited, nonexclusive, and world-wide license under U.S. Patent Nos. 7,358,542; 7,453,195; 7,497,973 ...
