This is a look back of Allegro’s A6267 released since 2012. The A6267 is a high current DC-DC converter that drives high power LEDs in series designed for automotive application. Driving the LEDs in ...

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 ...

With LED lighting becoming increasingly popular due to their high luminance, long life, high efficiency and decreasing costs, the subject of controlling and driving the LED's is now a very interesting ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

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 ...

LED controller with dual current regulation loops can detect faulty LEDs and provide 100:1 analogue dimming, writes Xin Qi, senior design engineer at Linear Technology. The LT3796-1 is a switching ...

STMicroelectronics has used the ‘CAN FD Light’ protocol in a 32-channel automotive lighting controller. “With 32 regulated current sources, independently programmable from 1mA to 15mA, L99LDLH32 can ...

This article introduces a DALI 2.0 slave software stack for XMC 1000 microcontrollers. This stack was developed by Infineon in close cooperation with Xenerqi and accelerates design of LED lighting ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

KP1601X is a high efficiency Buck LED power switch designed for LED backlight. It adopts quasi-resonant control mode and integrates accurate zero-crossing detection of inductor current, which can work ...

A couple years ago I got into making electronic conferences badges by building a device for DEFCON 25 shaped like a dragonfly. Like all badges the most important design factor was quite literally how ...
