The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard. The project accommodates the ...

The LDC-185 series of ac/dc LED drivers provide a constant current output, high efficiency, ac-input and rugged packaging needed for industrial lighting systems. Eight models operate from 90 to 305 ...

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

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 ...

Diodes Incorporated's AL5809, offered in a robust two-terminal PowerDI®-123 package, provides an improved accuracy, cost-effective solution for constant-current linear driving of LEDs. Diodes ...

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 ...
