DEMO MANUAL DC2218A
LT3965EFE
8-Switch Matrix LED Dimmer
DESCRIPTION
Demonstration circuit DC2218A is a matrix LED dimmer
system featuring the LT3965 8-switch matrix LED dimmer IC. There are 16 500mA LEDs that can be individually
turned on, off, or PWM dimmed with two 8-switch LED
dimmer LT3965 ICs. The two strings of LEDs are driven
with two buck LED driver outputs of the LT3797 triple LED
controller IC. The third channel of the LT3797 serves as a
30V pre-boost voltage regulator to provide a proper input
voltage to the two buck LED driver channels. DC2218A
can be driven from a 9V to 30V input and can survive
transients up to 36V.
A pre-programmed DC2026C Linduino™ One demo circuit
is attached to the DC2218A matrix LED dimmer shield to
create a full matrix LED dimmer system. With the Linduino
One attached as an under-shield microcontroller board, the
entire system can be powered from either a 9V to 36V lab
power supply or battery connected to the EMIVIN banana
jacks or from a 12V 4A+ AC/DC converter connected to
the J7 barrel jack connector.
PERFORMANCE SUMMARY
PARAMETER
DC2218A can be operated by connecting 12V power to the
input and selecting 7 pre-programmed patterns with rotary
switch S1. When connected to a PC through a USB cable,
an eighth setting of S1 (position 7) allows DC2218A to be
operated with a graphical user interface (GUI).
The LT3965 data sheet gives a complete description of
the part, operation and applications information. The data
sheet must be read in conjunction with this demo manual
for demonstration circuit DC2218A. The LT3965EFE is
assembled in a 28-lead plastic TSSOP (FE) package with
a thermally enhanced ground pad. Proper board layout
is essential for maximum thermal performance. See the
data sheet section Layout Considerations.

QUICK START PROCEDURE
How to Operate Pre-Programmed Patterns 0-6 (S1)
6. Change the Pattern Select rotary switch to positions
0-6 to observe different patterns.
Demonstration circuit DC2218A is easy to set up to evaluate the performance of the LT3965 matrix LED dimming
system and its pre-programmed patterns.
7. Press the Reset button S2 to start over again.
NOTE: The included DC2026C Linduino One is preprogrammed to work with DC2218A. If the .ino code is
mistakenly changed or overwritten, new .ino code must
be uploaded from Linear’s website.
Demonstration circuit DC2218A can be connected with a
PC via USB cable and controlled with a GUI.
NOTE: An acrylic shield has been assembled over the LEDs
to protect the user’s eyes from extremely bright light. Please
make sure that the shield is in place and any necessary
protective eyewear is worn before looking directly at the
bright LEDs and their patterns.
Follow the procedure below:
1. Set the PATTERN SELECT rotary switch S1 to any position between 0 and 6. Position 7 is reserved for use
with the GUI (graphical user interface).
2. Connect 12V power to either the EMIVIN and GND
banana jacks or to the J7 2.1mm (inside diameter)
barrel jack.
3. Observe the red LED indicator light (D32). When it
begins flashing, then the board is ready to start up.
How to Operate with Graphical User Interface (GUI)
NOTE: The included DC2026C Linduino One is preprogrammed to work with DC2218A and to interface with
the LT3965 GUI. If the .ino code is mistakenly changed
or overwritten, new .ino code must be uploaded from
Linear’s website.
NOTE: An acrylic shield has been assembled over the LEDs
to protect the user’s eyes from extremely bright light. Please
make sure that the shield is in place and any necessary
protective eyewear is worn before looking directly at the
bright LEDs and their patterns.
Follow the procedure below:
1. If never done before, download and install QuikEval™
from Linear’s website under design tools and software
at http://www.linear.com/designtools/software/#Data
QuikEval is your link to receiving the latest LT3965 GUI
software and to run the GUI. Installation of QuikEval
properly initializes the serial port driver on the computer
to work with the Linduino One USB connection.
If QuikEval is already installed, skip step 1, or update
QuikEval to get the LT3965 GUI.
4. When the red LED (D32) is flashing, push the Push to
Start button S3.
5. Observe the LED patterns and adjust the speed, brightness and pattern of the LEDs with the manual blue
potentiometer R14.

QUICK START PROCEDURE
2. Remove power and the USB cable from the DC2218A
inputs.
8. Observe the GUI program starts at ALL CHANNEL
MODE screen and the LEDs on the PCB are all off.
3. Turn the PATTERN SELECT rotary switch S1 to position
7 for the GUI.
9. Start creating and testing I2C commands with ALL
CHANNEL MODE, SINGLE CHANNEL MODE, BROADCAST, DIGITAL WRITE, READ REGISTERS, and LED
SETTINGS pages.
4. Connect 12V power to either the EMIVIN and GND
banana jacks or to the J7 2.1mm (inside diameter)
barrel jack.
5. Connect a USB cable between a PC and the USB connector on the under-shield DC2026C (which arrives
included in the DC2218A package and pre-programmed
with DC2218A .ino code).
NOTE: An LT3965 GUI user guide is posted on the Linear
blog site. It contains the GUI commands and details.
Please contact Linear support for help with the GUI and
User Guide.
6. Launch the LT3965 GUI from QuikEval.
7. Click Connect to DC2218A to connect to the DC2218A
with the GUI.

S1 Pattern Select Position
0. Comet: A comet of light runs around the sixteen LEDs
changing PWM dimming brightness quickly increasing
and decreasing at rates that look like a ball of fire zipping
around the LEDs. The interactive potentiometer controls
the speed of the comet.
1. Wave: A wave of light from right to left and from left to
right changing PWM dimming brightness quickly increasing and decreasing at rates that look like a wave running
from one side of the LEDs to the other. The interactive
potentiometer controls the speed of the wave.
2. Side-to-Side Steer: Center headlight LEDs stay on to
face directly forward while the right and left side LEDs
turn on with brightness proportional to the amount that
the steering wheel (interactive potentiometer) is turned.
3. High Beam Blank: While the low beam Is on 100%
brightness, the sections of the high beam turn OFF.
Although the blank spots would be controlled by a sophisticated camera detecting an object in front of a car
to determine which high beam LEDs to turn off or dim,
the section on DC2218A is controlled by turning the
interactive potentiometer.
4. Side Bend Steer: All sixteen LEDs adjust PWM dimming duty cycle and brightness based upon the position
of the steering wheel (interactive potentiometer). This
pattern represents a light that bends around the side of
a car, projecting a turning headlight pattern that is linked
to the steering wheel.
5. PWM All 16: All sixteen LEDs have the same PWM
dimming and brightness level that is set by the interactive
potentiometer. They range from OFF to ON In increments
of 1/256 PWM dimming.
6. Fade Wave: Using the PWM dim WITH FADE commands,
a wave of light is created by fading the LED brightnesses
up and down. WITH FADE option uses the logarithmic fade
function of the LT3965 and allows the brightness to fade
from low to high or from high to low with a single I2C bus
command. This pattern has low bus traffic.
7. GUI: GRAPHICAL USER INTERFACE position setting –
Use this position when connecting to the GUI. See details
above for downloading and connecting to the GUI via the
USB cable connection of DC2026C.
