To emulate the natural soft start of an incandescent bulb, this circuit makes use of the thermal-foldback protection built into an LED-driver IC (MAX16832). It thereby avoids the annoying and almost ...

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 ...

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 ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...

Infineon Technologies AG has introduced the new LED driver IC ILD8150/E. It features an innovative hybrid dimming mode technology for achieving 0.5% of the target current. With a supply voltage range ...

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 ...

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 ...
