The circuit below illustrates powering a LED (or two) from the 120 volt AC line using a capacitor to drop the voltage and a small resistor to limit the inrush current. Since the capacitor must pass ...

This circuit, designed on request, has proven to be useful to indicate when the voltage in a power supply line is changing from 120V to 240Vac. It can be used in different circumstances and circuits, ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...

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 ...

The iML8684 claims improved circuit stability in sub 3Vac situations created by TRIAC dimming, resulting in superior light quality at low dimming. This improvement also increases the number of ...

Fairchild introduced the new FL77944, a family of LED Direct AC Drives that manufacturers can use to easily scale power and create smart and scalable LED-based lighting. Fairchild introduced the new ...
