White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...

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 ...

Parallel LED drivers can be used to create the fast, square, high-current waveforms required for automated image processing. And it’s possible to extend such waveforms to higher currents by connecting ...

144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...

[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...
