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 ...

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 ...

The MAX16820 step-down constant-current high-brightness LED (HB LED) drivers provide a cost-effective solution for architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination ...

ROHM’s new series of automotive-focused matrix LED drivers combines an 8-line switch controller with 24-channel current driver, bringing control (dimming) to up to 192 zones of mini-LEDs for ...

Allegro Microsystems, LLC announces the release of the A6271, a DC-DC converter controller that offers a programmable constant current output for driving high power LEDs in series. The A6271 ...

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 ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

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 ...
