International Rectifier, IR®, a world leader in power management technology, introduced the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other ...
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 ...
LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter is ...
Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...
Toshiba Electronics Europe has introduced the TB67S559FTG 50V/3.0A stepper motor driver IC that supports constant current control with built-in current detection. 50V/3.0A constant current stepper ...
Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...
