Quick-Start Procedure
This quick-start assumes default conditions as shipped.
1. Power up the DLP LightCrafter™ Display 3010 EVM Gen2 by applying an external DC power supply
(19 V DC, 4.75 A) to the J9 connector.
External Power Supply Requirements:
•
Nominal Output Voltage: 19 VDC
•
Minimum Output Current: 2.5 A; Max Output Current: 4.74 A
•
Efficiency Level: VI
NOTE: TI recommends using an external power supply that complies with applicable regional safety
standards such as UL, CSA, VDE, CCC, PSE, etc.
NOTE: The system is designed to operate also with an external 12-V DC power supply. The P5V_VIN
(D9) and P3P3V_SB (D10) LED will turn on to indicate that 5-V and 3.3-V standby power is applied.
