DESCRIPTION
Positive terminal of C2
Charge pump output
Current sense input. Connect 1% resistor to ground to set constant current through
LED
Enable for Group-B LEDs (D5~D6). Logic input High=Group-B LEDs ON.
Low=GroupB LEDs OFF. Pulsing this pin with a PWM signal (100Hz-1kHz) can
be used to dim LEDs.
Enable for Group-A LEDs (D1~D4). Logic input High=Group-A LEDs ON.
Low=GroupA LEDs OFF. Pulsing this pin with a PWM signal (100Hz-1kHz) can be
used to dim LEDs.
Current source outputs. Connect directly to LED
Power supply ground input
Negative terminal of C1
Power supply voltage input
