Pin Descriptions
Input voltage. Input range: 2.7V to 5.5V.
Ground
Charge pump output. Approximately 1.5xV
IN
Flying capacitor connections.
A1, B2, A5, E1
A7
Enable pin. Logic input. High = normal operation, Low = shutdown (charge
pump and all current sources OFF).

LED Outputs - Group B
Enable for Group-A LEDs (current outputs). Logic input.
High = Group-A LEDs ON. Low = Group A LEDs OFF.
Pulsing this pin with a PWM signal (100Hz-1kHz) can be used to dim LEDs.
Enable for Group-B LEDs (current outputs). Logic input.
High = Group-B LEDs ON. Low = Group B LEDs OFF.
Pulsing this pin with a PWM signal (100Hz-1kHz) can be used to dim LEDs.
Placing a resistor (R
SET
) between this pin and GND sets the LED current for
all LEDs. LED Current = 100 x (1.25V ÷ R
SET
).
