In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

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 ...

Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...

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 ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate 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 ...

Linear Technology has announced the LT3909, a high efficiency, constant current LED driver that can drive two strings of up to 10 LEDs at 50mA. To ensure constant brightness, each LED string contains ...

MILPITAS, Calif., July 10, 2023 (GLOBE NEWSWIRE) — Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI), announces the release of its latest LED driver IC for controlling ...
