When designing a handheld device with a color display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

This article will explain the basic operation and configuration of a simple parallel strings LED driver. Examples and illustrations are also shown for better understanding together with its advantages ...

The FAN5607 constant-current parallel LED driver from Fairchild Semiconductor provides analog and/or pulse-width-modulation brightness control for LCD backlighting in ultra-portable applications. It ...

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

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 ...

Rohm has introduced a linear LED driver for automotive use, following close on the heels of its LED driver for motorcycles. BD18336NUF-M is a 3 x 3 x 1mm constant current driver IC that can deliver ...

White LEDs (WLED) are increasingly becoming the light source of choice for backlighting applications due to their attractiveness in power efficiency and form factor. Display solutions in portable ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...

[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...

[Neil] is driving this Siemens A60 LCD using a parallel port on his Linux box. He likes this module because it has an integrated LED back-light, controller IC, and the pads are large enough for a ...
