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 ...
You can use an LED as a photoelectricsensor. A previousDesign Idea shows that such a switchis highly power-efficient, consumingalmost no power (Reference 1).However, you cannot adjust that ...
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 ...
LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...
Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...
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 ...
