The LED backlight in an LCD panel is the biggest power hog in notebook and tablet applications. As screen resolution and brightness level increase, the input power consumed by the LED backlight ...

Several driver options are at the fingertips of designers with the FAN56XX family of LED drivers from Fairchild Semiconductor. For instance, driver-only parallel connection drivers with no boost ...

This is a reference design for an LED display-backlight driver. The design uses a boost power supply with adaptive feedback for efficiency and linear current sinks for a high dimming ratio (2000:1).

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 ...

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 ...
