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 ...

Here is a look back of Allegro’s A8515, a wide input voltage range, high efficiency fault tolerant white LED driver. The device was made available in the market since 2010. It features multiple output ...

[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 ...

Most small-size color LCD displays today use white LEDs for backlighting. These systems usually involve handheld devices with an LED drive circuit powered by a battery whose output voltage varies over ...

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 ...

Osram Opto is claiming “one of the best values in the world in terms of forward voltage for blue high-current chips” following improvements in epitaxy, leading to up to 8% efficiency improvement. Some ...

The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...

Experience low power, high security, and reliable performance with PolarFire® Core & SoC FPGAs. A maker recently engineered ...
