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 ...

This slideshow is based on the LEDs Design Ideas Collection, a collection of LED-related reader submitted circuits and design applications that have appeared in EDN's 'Design Ideas' section. Here you ...

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 ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
