Description
LED2 Current Source Output. D2 is the output of LED2 current source. Connect LED2’s anode to D2
and its cathode to GND.
LED1 Current Source Output. D1 is the output of LED1 current source. Connect LED1’s anode to D1
and its cathode to GND.
Charge Pump Output. OUT is the output of the charge pump. Bypass OUT to GND with a 1μF or
larger ceramic capacitor.
Charge Pump Capacitor Negative Node.
Charge Pump Capacitor Positive Node. Connect a 1μF ceramic capacitor between C+ and C-.
Analog Ground. Connect this pin to the system’s analog ground plane.
LED Enable and serial control input. EN/SET is the ON/OFF control for the LED and the S
input for the AAT3104-1/-2 to control serially the LED brightness according to the maximum current.
Power source input. Connect IN to the power source, typically the battery. Bypass IN to GND with a
1μF or larger ceramic capacitor.
LED4 Current Source Output. D4 is the output of LED4 current source. Connect LED4’s anode to D4
and its cathode to GND.
LED3 Current Source Output. D3 is the output of LED3 current source. Connect LED3’s anode to D3
and its cathode to GND.
