Overview
Product Details
Demonstration circuit 1608A features the LT3745, a 16-channel 50mA buck LED driver controller and serial interface. Each channel drives a single LED. Three LT3745's are connected in series with each one controlling a color in a 16 LED RGD array. Each channel has an individually adjustable 12-bit (4096-step) grayscale PWM dimming control and a 6-bit (64-step) dot correction current adjustment.
The demo board input voltage range is 9V to 40V and the buck controller outputs 3.4V or 4.2V depending on the color of the LED.
