SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

This file type includes high resolution graphics and schematics when applicable. Light-emitting diodes (LEDs) are semiconductor devices that emit light when an electrical current passes through ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

In Part 1 of this three-part series, we discussed the importance of a well-engineered PCB ground plane for LED drivers, so the ground plane can be effective in managing disturbance energy generated ...

The adoption of LEDs continues to expand across a variety of sectors, including automotive, agricultural, industrial, commercial, and outdoor lighting. The biggest growth drivers are their lower power ...

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 ...
