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 ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

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 ...

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 ...

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 ...

Along with being brighter, LED bulbs tend to use less power and have a much longer average lifespan compared to conventional halogen bulbs. Now that LED lighting technology has gotten significantly ...
