DEMO MANUAL DC2630A

Rev. 0

4.  Download the Linduino code and library files from 

the DC2630A web page.

5.  Upload the code to the connected Linduino 

demo circuit.

6.  With power off, connect a string of up to 16 LEDs 

between each channel’s LED

+

 and GND turrets. 

Connect the EN/UVLO turret to GND to keep the cir-

cuit shut down. With the power off, connect the input 

power supply to the V

IN

 and GND terminals.

7.  For I

2

C serial communications, set JP1 (ADDR1) 

to 1 and JP2 (ADDR2) to 1. This is the chosen I

2

address for the DC2630A command line interface.

8.  Open up the serial monitor inside Arduino IDE.
9.  Turn on 12V power to the V

IN

 and GND pins of 

the DC2630A.

10.  Use command line interface in serial monitor to eval-

uate the performance of the LT3966 demo circuit.
