DLP5531-Q1 Light Engine Evaluation Module User's Guide
TI's DLP® technology offers the highest resolution available for automotive headlight applications and it's
fully programmable. With more than one million addressable pixels per headlight, DLP technology
exceeds the resolution of existing adaptive driving beam (ADB) technologies by serval orders of
magnitude. Automakers and Tier-1 suppliers can use this new programmable ADB solution to maximize
brightness for drivers while minimizing the glare of oncoming traffic and reflections from high-gloss traffic
signs. DLP technology works with any light source, including LED and laser illumination, and gives
designers more precise light distribution on the road, with customizable beam patterns controlled by
programmable software. Automakers and Tier-1 suppliers can partially or fully dim individual pixels with
this solution, paving the way for the creation of headlight systems that allow drivers to keep their
highbeams on in any condition.
The DLP5531-Q1 Light Engine Evaluation Module (EVM) allows for accelerated evaluation of the
DLP5531-Q1 chipset with the inclusion of a DLP5531-Q1 light engine. This module brings together a set
of components including the DLP5531-Q1, the DLPC230-Q1, and the TPS99000-Q1 to provide an
efficient system for evaluation of high resolution headlight technology. When combined with an input video
source and a computer or other means of control, the evaluation module can be used in a laboratory
setting to demonstrate features such as:
• Adaptive Driving Beams
• Glare-Free Beam Steering
• Reflective Traffic Sign Dimming
• Pedestrian Dimming
• Symbol Projection
• OEM Branding

Care must be taken to ensure that individual components and PCB do not exceed their maximum temperature when driving
high-power load.
Some components are only rated to 85°C. Refer to Table 9 for a list of these components.
Component Temperature Ratings
The boards and most of the board components are rated to operate between –40°C to 105°C, including
the DLP5531-Q1, the DLPC230-Q1, and the TPS99000-Q1.
Some components on board, such as switches, connectors, and indicator LEDs, do not meet this
temperature rating. The specifications for all EVM components which are not rated between –40°C to
105°C are listed in Table 9. Please refer to the EVM bill of materials to review the temperature

Driver Requirements
The DLP5531-Q1 chipset, used with LED illumination, requires illumination modulation. This illumination
modulation turns off the light output during micromirror reset, which improves system contrast. For the
system timing specifications of the DLP5531-Q1 Light Engine EVM, see Figure 4.

Quick Start
Use the following instructions to setup your DLP5531-Q1 Light Engine EVM and PC.
2.1
Kit Assembly Instructions
When assembling the DLP5531-Q1 Light Engine EVM, it is helpful to start by connecting the cables to the
formatter board (attached to the light engine) to the LED driver board. Once all of the cables are
connected, the light engine can be mounted. To mount the light engine, attach the light engine to the light
engine stand. After the light engine is mounted on the stand, the stand can be mounted on the mounting
plate of the LED driver board. A diagram of all connections is shown in Figure 5. The full light engine
assembly is shown in Figure 6.
1. Connect the Headlight Driver Interface cable to the Formatter Board (J10) and the LED Driver Board
(J5).
2. Connect the Host SPI cable to the Formatter Board (J2) and the Cheetah adapter. Connect the
Cheetah adapter’s USB cable to PC.
3. Connect the Formatter Power cable to the Formatter Board (J11) and the LED Driver Board (J1).
4. Connect the LED power cable to the LED Driver Board LED2 port (J9). The LED connector is located
between the heat pipes and heat sink of the DMD. This connector is above the formatter board.
5. Connect the Fan Power cable to any of the LED Driver Board fan ports (J3, J5, J6). Confirm the fan
switch on the LED Driver Board (SW1) is in the ON position.
6. Connect the Micro HDMI cable to the Formatter Board (J3). Connect the Micro HDMI cable to PC
HDMI port.
7. Connect the Power Input cable to the LED Driver Board (J2).

Power-Up
1. Connect input power cable to a power supply that meets input power specifications defined in
Section 1.2. The red cable for the V+ terminal and black cable for the V– terminal.
2. Turn on the supply power. Once powered up, a Formatter Board LED indicator (D6) should illuminate
green.
3. Turn the PROJ_ON switch (SW4) ON. The ON position is towards the perimeter of the board, and OFF
is towards the DMD. A Formatter Board LED indicator (D7) should illuminate green.
2.2.1
Software Setup
1. Download and install the DLPC230-Q1 Control Program (https://www.ti.com/mysecuresoftware).
2. Install Total Phase Cheetah USB adapter (http://www.totalphase.com/products/usb-driverswindows).
3. Use the DLPC230-Q1 Control Program to connect to the system using the Cheetah USB to SPI
adapter and turn the system on.
4. To connect, set the DLPC230-Q1 Host to SPI and select the Cheetah from the drop down menu.
Figure 7. Connecting to the DLPC230-Q1 Device Using the DLPC230-Q1 Automotive Control Program #1
5. Select "Connection Settings" to confirm the SPI configuration matches the Formatter Board switch
settings described in Table 2. Specifically, SPI mode and CRC/Checksum may vary based on switch
settings. Press "OK" once configuration is complete.

LED Driver
Section 1.2 defines the LED driver load specifications.
The LED brightness can be controlled through PWM output from the DLPC230-Q1. Using the DLPC230Q1 Automotive Control Program "Headlight Control" tab, the PWM slider bars (PWM0, PWM1, and
PWM2) control the current through each LED driver channel. Note that the PWM control may exceed the
maximum current specification of some LEDs in certain LED configurations. Table 12 provides reference
conversions from PWM level to drive current for commonly used current levels.

Some current will continue to flow through the LED with a PWM level of 0 and light output may still be visible. To fully remove
LED current, the system must be set to standby mode.
