The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

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 ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

Linear Technology announces the LT3744, a synchronous step-down DC/DC converter designed to deliver constant current to drive high current LEDs. Its 3.3V to 36V input voltage range makes it ideal for ...

Under the agreement, Cree LED has been granted by Current, a limited, nonexclusive, and world-wide license under U.S. Patent Nos. 7,358,542; 7,453,195; 7,497,973 ...

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 ...

Many of today’s portable electronics require backlight LED-driver solutions with the following features: direct control of current, high efficiency, PWM dimming, overvoltage protection, load ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...

Date Announced: 20 Dec 2007 Linear Technology has announced the LT3478 and LT3478-1, two 40V, 4.5A DC/DC converters designed to drive high current LEDs at constant current. Their 2.8V to 36V input ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...
