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 ...

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 ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

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 ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...
