DC749A

DC749A demonstration circuit is a multi-display LED controller featuring the LTC3206. The LTC3206 is a highly integrated multi-display LED controller. This device contains a high efficiency, low noise fractional step-up/step-down charge pump to provide power for a main and sub white LED display, plus an RGB colour LED display. The LTC3206 requires only four small ceramic capacitors plus two resistors to form a complete 3-panel LED power supply and a current controller. Maximum currents for the main/sub and RGB displays are set independently with a single resistor. Current for each LED is controlled with an internal current source. Dimming control for all displays is achieved via a 2-wire I2C interface. The RGB or Sub panel may be disabled with the ENRGB/S pin. Sixteen dimming states exist for the main panel, sub panel, and the red, green, and blue LEDs resulting in up to 4096 colour combinations.
