High-powered LEDs are used in a growing number of applications, including automotive lighting, camera-phone flash, entertainment lighting, location lighting, landscape lighting, flashlights, bicycle ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Modern automotive matrix lighting often utilizes strings and matrices of LEDs, requiring an increasing number of integrated circuits to control them. New designs must usually pack more electronics in ...

Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...

But there’s a problem with this idea. First, the resistor will possibly dissipate a large amount of power. For instance, a resistor used to drop 12 V (a common voltage used for halogen task lighting) ...
