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 ...

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

[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 ...

This file type includes high resolution graphics and schematics when applicable. The circuit in Figure 1 uses a bicolor (red/green) LED to indicate the voltage measured with a set of three color ...

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 ...
