: Though the LED driver of the EVM is capable of driving above 1 A per channel, TI does not recommend driving beyond 500 mA for
extended periods to prevent damage to the EVM due to individual component temperature ratings and thermal management limitations.

: Values based on DLP3021LEQ1EVM LED Part Numbers at 500-mA driver:
• Green: Osram LCG H9RM-LXMX-1
• Red and Blue: Osram LE BR Q7WM-TGTI-24+JXJZ-23

: Some components are only rated to 85°C.
1.3.2 Component Temperature Ratings
The board and most of the board components are rated to operate between –40°C to 105°C, including the
DLP3021-Q1, MSP430 MCU, and FPGA DMD controller. Some components on board, such as switches,
connectors, and indicator LEDs, do not meet this temperature rating. Please refer to the EVM bill of materials to
review the temperature specifications of all components used in the EVM design.
1.3.3 LED Driver Design
The DLP3021-Q1 chipset, used with LED illumination, includes illumination modulation based on the LM3904-
Q1 P-FET buck controller for high-power LEDs. This illumination modulation turns off the light output
