A pair of dc-dc converters are specifically designed to drive high-current LEDs at a constant current. The LT3478EFE and LT3478EFE-1 from Linear Technology feature a 2.8- to 36-V input range that is ...

High-powered LEDs are used in a growing number of applications, including automotive lighting, camera-phone flash, entertainment lighting, location lighting, landscape lighting, flashlights, bicycle ...

Woburn, MA — Innovations in Optics, Inc. introduces the Model 5000A-100 LED driver/controller for powering its patented and patent-pending high power LED light engines. The 5000A-100 LED driver ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

To match the brightness and color of multiple LEDs in RGB applications you should drive all LEDs with a constant current. However, some of these driver ICs require the complication of microprocessor ...

In my previous column, we covered quite a lot of ground, starting with the first vacuum tube diodes, moving to their solid-state (semiconductor) descendants, and progressing to their light-emitting ...

Driving more than a handful of LEDs from a microcontroller is often a feat that takes tedious wiring, tricking the processor, or a lot of extra external hardware. Charlieplexing is perhaps the most ...
