Keywords:LTC3207? LED driver? universal LEDs?

The LTC3207/LTC3207-1 is a 600mA LED/camera driver that illuminates 12 Universal LEDs (ULEDs) and one camera flash LED. The ULEDs are considered universal because they may be individually turned on or off, set in general purpose output (GPO) mode, set to blink at a selected on-time and period, or gradate on and off at a selected gradation rate. This device also has an external enable pin that may be used to blink, gradate, or turn on/off the LEDs without using the I?C bus. This may be useful if the microprocessor is in sleep or standby mode. If used properly, these features may save valuable memory space, programming time and reduce the I?C traffic.
