This is a project circuit in which we use PWM to dim the intensity of light of the LED. The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. If you want to control the ...
Find a downloadable version of this story in pdf format at the end of the story. EXPONENTIAL GROWTH of LED lighting has ushered in a vast selection of integrated circuit devices to provide controlled ...
Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s and an Arduino together, cobble together some code from the examples in the FastLED library, and call it a day. We ...
In part one of this series, we looked at the basics of LED lighting sources and their driving requirements. In part two, we discussed why a constant-current buck converter should be your first ...
Diodes has launched a boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications. The AL8853AQ is an automotive-compliant and highly integrated ...
Ricoh has introduced its first LED lighting chip – apart from the camera/phone LED controller it makes. R1580 is a dc-fed constant-current LED driver controller that needs on mosfet and a handful of ...

What is PWM dimming, and what are the alternatives?
Have you ever looked at your phone and gotten a headache? Sometimes, it just means you've been on it too long and need to take a break. For some folks like me, it's the display itself that's causing ...
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, ...
