Universal LED Driver Features

360mA Output Current, Independent Control Of 18 LEDs with Low Noise and up to 91% Efficiency

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation announces the LTC3220/-1, an inductorless, low noise, high efficiency LED driver for cell phone displays and other programmable lighting applications. The IC provides 18 individually configurable LED current sources for complete flexibility in programming multiple displays. The display currents are set via a precision internal current reference. The universal current sources can be digitally controlled with independent dimming, brightness, blinking, and gradation control, programmable via a simple two-wire I2C serial interface; LTC3220 and LTC3220-1 each offer a unique I2C address. The LTC3220/-1’s 2.9V to 5.5V input voltage range has been optimized for single-cell Li-Ion/Polymer battery applications.
