Catalyst Semiconductor, Inc. has expanded its line of patented Quad-Mode fractional charge pump LED drivers with a new device optimized for portable products. The CAT3637 addresses the requirements for high-efficiency and easy LED programming in portable devices, with 10 percent higher efficiency when compared to three-mode charge pumps, and a simple, 1-wire EZDim interface control.

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.
