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 ...

The HV9803 is a LED driver IC with average-mode constant current control and operates in a constant off-time mode. It can be powered from a 7.0 – 13.2 V supply. The device is equipped with a current ...

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 ...
