4.5.1 DLP LightCrafter Single DLPC900 LED Enable and PWM Outputs

The LED enables on J23 are low-current 3.3V outputs and are not to be used to drive LEDs directly. The enables are to be used as a control to enable a regulator that provides the necessary current to the LEDs. The PWM outputs are also 3.3V outputs and used for controlling the current to the LEDs, which controls the brightness.

Note:

The 12V DC output on J23 is not to be used to power the LED drive circuitry since the output does not provide the necessary current when all three LED enables are simultaneous turned on. Doing so can cause a drop in the 12V supply to the EVM regulator circuitry and reset the controller.
