Texas Instruments Incorporated introduced a new LED controller with constant power regulation. The LM3447 AC/DC LED driver includes a dimmer detect, phase decoder and adjustable hold current circuits ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Integrated Silicon Solution’s (ISSI) IS31LT3932 LED controller offers a universal input voltage range from 85 to 265 V ac, power factor correction greater than 0.97, and typical output current ...

National Semiconductor’s constant-current controller enables off-line, uniform, flicker-free dimming of high-brightness light-emitting diodes (LEDs) with a conventional TRIode for Alternating Current ...

The demands on the ordinary light fixture have dramatically increased in recent years. Commercial buildings have started using lighting to attract customers, consumers have started looking for more ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...
