Universal Cell Phone LED/CAM Driver Features 600mA Total Output Current & 92% Efficiency

Linear Technology Corporation announces the LTC3207, an inductorless, low noise, high efficiency LED/CAM driver for cell phone displays and lighting. The IC provides 12 individually configurable current sources for Main, Sub, RGB, Auxiliary or general purpose (GPO) displays/lights/outputs, plus drive capability for one high-current 400mA LED camera light. The universal current sources have digital control with independent dimming, brightness, blinking, and gradation control, programmable via a simple two-wire I2C serial interface. Camera flash (pulsed) or torch (continuous) current levels can be selected real time by the CAMHL pin or alternatively can be controlled by the I2C port.
