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 ...

Diodes Incorporated today announced the release of the AL8806 buck LED driver, capable of producing a constant current of up to 1.5A from voltage sources of between 6V and 30V. Suiting MR16, 12V and ...

[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 ...

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 ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...

Leading manufacturer and supplier of explosion proof lighting equipment Larson Electronics has announced the release of a new pedestal mount LED work light configured to work on 24 volts DC or AC. The ...

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 ...

Littelfuse has introduced an optically isolated photovoltaic gate driver for mosfets and IGBTs. Essentially, photovoltaic gate drivers are opto-isolated relays without the internal output mosfets, ...
