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 ...
This application note is intended for engineers designing an isolated AC-DC LED driver using the LinkSwitch-PH family of devices. It provides guidelines to enable an engineer to quickly select key ...
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 quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
