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 ...

DURHAM, N.C.--(BUSINESS WIRE)--Cree LED, an SGH company (Nasdaq: SGH), and Current Lighting Solutions, LLC announced that they entered into a patent license agreement, effective October 2022, with ...

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 ...

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 ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

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 ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

CLEVELAND--(BUSINESS WIRE)--GE Current, a Daintree company is proud to announce the latest addition to its rapidly growing Type B Double-Ended product portfolio, the XL. The XL is Current’s take on ...

This relatively simple circuit uses a 6-V DC supply with a PWM current-source configuration to provide efficient, adjustable dimming of a white LED over a wide range, needed to accommodate the unique ...
