Infineon has brought out a constant current linear LED driver IC which provides low-voltage drop performance for regulating LED current. It is the second device released in the new generation BCR ...

This file type includes high-resolution graphics and schematics when applicable. Many applications for LED illumination require wide dimming ratios, which can be easily done using an adjustable ...

[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 ...

Linear Technology has announced the LTC3218, an inductorless high current white LED driver that delivers up to 400mA of LED current. Its multi-mode architecture automatically switches between 1x or 2x ...

The project is originally designed as LED calculator but the addition of a rotary encoder to set the target system voltage results to adjusting the LED brightness using the potentiometer. By turning ...

An LCD module DMC-16207 of 2×16 was used for prototyping the LED calculator since it uses the Hitachi chipset to produce a view around 3 ½” wide. An LCD module DMC-16207 of 2×16 was used for ...

LED-based bulbs that replace their incandescent counterparts require a significant amount of engineering (Fig. 1). In the 60 W range the LED driver board can take up about 15% of the overall cost of ...
