Main power supply for outputs.
Common ground reference.
Apply a DC voltage or a PWM voltage to this pin to adjust the LCD1
output voltage. PWM inputs should be greater than 120Hz.
Pulled up to VIN on board (10K
), Ground to inhibit the LED driver
output (VOUT).
Pulled up to VIN on board (10K
), Ground to inhibit the VLCD1.
Output voltage test point. Programmed for 18V output, adjustable up to
25V.
Output voltage mirror of VLCD1
LED drive voltage probe point.
LED current sense feedback.
Apply a DC voltage or a PWM voltage to this pin to adjust the LED
