LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

When designing a handheld device with a color display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

The FAN5607 constant-current parallel LED driver from Fairchild Semiconductor provides analog and/or pulse-width-modulation brightness control for LCD backlighting in ultra-portable applications. It ...

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 ...

Abstract: A parallel LED string driver using capacitors for source and string ground separation is proposed. The methodology is based on connecting multiple transformers in a daisy chain and using ...

WS2812 strips are slow for writing data, with a data rate of just 800khz, it takes 30µs to write out a single led's worth of data. One way to improve the performance here is with parallel output, ...

Abstract: High-frequency ac (HFAC) power distribution system has a broad applications caused by the components saving, weight reduction, and efficiency improvement. Meanwhile, light-emitting diode ...

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 ...

FastLED-friendly LED display driver allows for configuration and control of multiple LED display devices independently in code. Display objects use DMA transfer (from OctoWS2811 library) on any or all ...
