Analog Devices LT3745 | Demoboard DC1608A

Beschreibung

Demonstration circuit 1608A features the LT®3745, 16-channel 50mA LED driver with buck controller and serial interface. Each channel has an individually adjustable 12-bit (4096-step) grayscale PWM dimming control and a 6-bit (64-step) dot correction current adjustment. Both dimming control and current adjustment are accessible via a 30MHz cascadable serial data interface. Individual open/short LED and overtemperature flags are sent back during status read back.

Three LT3745’s are connected in series to control 16 RGB LEDs stuffed on the demo board. Each IC drives a separate color. The evaluation software installed in a host computer communicates with the DC1608A via the interface board DC590B, an USB serial controller.

The LT3745 data sheet gives a complete description of the part, its operation and application information. The datasheet must be read in conjunction with this quick start guide for working on or modifying the demo circuit 1608A.
