Editors’ Note: This segment is adapted from Chapter 3 of Power Supplies for LED Driving by Steve Winder. We have seen in Chapter 2 that an LED behaves like a constant voltage load with low equivalent ...

Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...

This file type includes high-resolution graphics and schematics when applicable. Many applications for LED illumination require wide dimming ratios, which can be easily done using an adjustable ...

Oh God, here we go....<BR><BR>LED's are current devices, not voltage devices. If the LED you have has a 3V voltage drop, then subtract the 3V from your source and use that voltage to calculate the ...

Find a downloadable version of this story in pdf format at the end of the story. With the rising costs of energy and increasing governmental requirements for high efficiency lighting, the high ...

I'm wondering what the generally accepted rules are about what the maximum draw on a motherboard's led connectors is. I'm thinking about hooking up 2-3 leds per function (hdd, pwr, etc) and want to ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string of roadway, walkway, or parking ...

Power integrity is becoming a bigger problem at 10/7nm because existing tools such as static analysis no longer are sufficient. Power integrity is a function of static and dynamic voltage drop in the ...
