PRODUCTION DATA
Several situations exist in which the control loop for the buck converter via the LED is not present. To prevent the output voltage of the buck converter to "run-away," the loop is closed by means of an internal resistive divider (see Figure 8-4—Openloop feedback circuitry). Situations in which the openloop voltage control is active:
