LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

A constant current is better than a constant voltage for driving LEDs. In this proposed circuit, a common constant-voltage regulator is changed into a constant-current source for LEDs. In addition, a ...

True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED ...
