Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Digi-Key Technologies has developed a diagramming tool that includes a comprehensive electronic symbol library and an integrated Digi-Key component catalog that allows for a wide range of circuit ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

Here, we have described a simple circuit named “Mains operated LED Lights” which you can easily made and install in your homes. This is a simple circuit named Mains Operated LED Lights which you can ...

This idea describes a white- LED (WLED) driver circuit controlled by a simple ambient light sensor (ALS). A typical application would be a brightness control for cell-phone backlighting. On a very ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...
