LTC3209-1/LTC3209-2 600mA Main/Camera LED Controller DESCRIPTIO The LTC ®3209-1/LTC3209-2 are highly integrated multidisplay LED controllers. These parts contain a high efficiency, low noise charge pump to provide power to MAIN, CAM and AUX LED displays. The LTC3209-1/ LTC3209-2 require only four small ceramic capacitors and one current set resistor to form a complete LED power supply and current controller. The maximum display currents are set by a single external resistor. Current for each LED is controlled by a precision internal current source. Dimming and On/Off for all displays is achieved via the I2C serial interface. 256 states are available for the MAIN display. Sixteen states are available for the CAM display and four states are available for the AUX display.
