This issue's products focus mostly on LEDs and EVs, but don't miss previews of two must-attend power design conferences as well as a deep-dive tutorial on dc supply stability.

Start with the basics LEDs begin to produce light once their supply voltage is equal to or greater than the diode's forward voltage drop (typically in the region of 2-3V). The current required for ...

I was searching for a LED driver that can also act as dimmer for my 10 watts LEDs and found the PT4115 IC which is kind of interesting. It operates from an input supply between 6V and 30V and provides ...

LED dimming isn't just for mood lighting. Here's how digital controllers can handle dimming chores necessary for creating multicolor displays.

There are plenty of utilities out there to control keyboard LED indicators, but I'm rather interested in controlling the power LED on my headless 1U rackmount. While theoretically there are tons ...
