LED Drivers and DC to DC Converters

LED drivers boost a low-level DC battery voltage to the high voltage needed to drive high-brightness LEDs. Target applications for LED drivers include backlighting of LCD displays in PDAs, MP3 players, Cell Phones, GPS terminals and digital cameras. In addition, LEDs drivers are used for backlighting keypads, camera flash equipment and illumination in automotive markets.
