While we have now published quite a few LED driver circuits, to date we have not published a design to drive a bunch of high-brightness white LEDs. Such a circuit is now quite desirable as the price ...

This driver circuit reference design is an ideal choice for powering a small number (about 2 to 6) LEDs. Advantages include a small PCB form factor of 5.7cm x 3.1mm, wide input and output voltage ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

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 Idea for Design presents a simple and small solution for driving an LED to provide visual feedback in the presence/absence of a system’s power. Typical requirements for industrial LEDs. Designing ...

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also great example ...

Cold-cathode fluorescent display backlights are compared/contrasted to LED backlights, and the differences in driver circuits for both are discussed. CCFL backlights are the most common backlight ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the ...
