LED-based bulbs that replace their incandescent counterparts require a significant amount of engineering (Fig. 1). In the 60 W range the LED driver board can take up about 15% of the overall cost of ...
High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...
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 ...
The high efficiency of more than 93 % at heavy load with 1 Ampere and three LEDs in series as well as 85 % at light load with 0.35 Ampere and one LED allows the usage of a very small PCB. The LED ...
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 ...
ZHUHAI, GUANGDONG, CHINA, January 21, 2026 /EINPresswire.com/ -- As global demand for intelligent, energy-efficient ...
A programmable multi-output LED driver from Allegro MicroSystems, LLC suits LCD backlighting, instrument clusters, and daytime running lights. Allegro's™ A8517 integrates a current-mode boost ...
Lumissil Microsystems has created a pair of LED drivers that include a 32MHz 8051 microcontroller. “These new controllers enable lighting engineers to create customised dynamic LED lighting animations ...
