GlacialPower announces a new dual-mode LED driver powering LED lighting from 7W to 20W. Featuring either constant current or constant voltage operation, the LED driver mode and power output can be ...

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 ...

[Afroman] contacted us to share his new video on the LM317. The humble LM317 adjustable voltage regulator is everywhere. From wifi routers, to high spec lab equipment. Given a noisy input and a ...

The current sink project aims to provide test for power supplies as well as obtaining the amount of current of an LED. The circuit automatically adjusts its effective resistance to maintain a constant ...

As the demand for smaller LED lighting installations that also provide high efficiency and ultra-low EMI grows, so Diodes Incorporated has extended its BCR420U and BCR421U families of linear LED ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...
