LEDs for lighting are found anywhere from DIY IoT modules to commercial lighting applications and the cabins of airplanes. To run properly, these critical lighting devices require a precise balance of ...

A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

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 ...

Infineon has brought out a constant current linear LED driver IC which provides low-voltage drop performance for regulating LED current. It is the second device released in the new generation BCR ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

LEDs are nonlinear devices with I/V curves that resemble the curves of rectifier diodes. Designers of lighting drivers require a good approach to modeling the LED device performance in the first ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

NEW DELHI: If you are following the LED technology closely, then you might have heard about the term - LED drivers. This is one of the crucial and confusing parts of the LED lighting because there is ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
