White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...

The Fairchild FAN5611/12/13/14 low-dropout product family is designed to drive two to four parallel LEDs, providing matched current source bias for all color LEDs. The LED current is set by an ...

Targeting white LED applications, the AQ9156 switched-capacitor regulator provides a regulated 4.5V output at up to 120 mA and can drive up to six parallel LEDs. Typical input voltage ranges from 3V ...

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 ...

[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 ...
