Pin Description
Connect this pin to the positive terminal of C2.
Regulated Charge pump output (4.35V).
Connect this pin to the positive terminal of C1.
Current source output 3. Connect directly to LED.
Current source output 2. Connect directly to LED.
Current source output 1. Connect directly to LED.
Current set input. Value of resistor tied between I
SET
and GND sets the Dx
output currents.
No Connect
Enable Input High = On, Low = Shutdown
Current Source Modulation pin. High = On, Low = Off. Applying a PWM signal
to this pin allows the regulated current sources to be to be modulated without
shutting down the V
OUT
pin and the remainder of the part.
Power supply voltage input.
Connect this pin to the negative terminal of C2.
Ground connection.
Connect this pin to the negative terminal of C1.
