Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...

This article will explain the basic operation and configuration of a simple parallel strings LED driver. Examples and illustrations are also shown for better understanding together with its advantages ...

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 ...

Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...

Sony says that Crystal LED will be developed in “parallel” to OLED for future consumer and professional applications. Sony says that Crystal LED will be developed in “parallel” to OLED for future ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...
