PIN FUNCTIONS
LED1 (Pin 1): Connection point for the anode of the ?rst
LED of the ?rst set of LEDs and the sense resistor (R SENSE1 ).
The LED current can be programmed by:
CAP2 (Pin 6): Output of Converter 2. This pin is connected
to the cathode of internal Schottky diode 2. Connect the
output capacitor to this pin and the sense resistor (R SENSE2 )
I LED 1 =
200mV
R SENSE 1
from this pin to LED2 pin.
SW2 (Pin 7): Switch Pin. Minimize trace area at this pin
to minimize EMI. Connect the inductor at this pin.
CTRL1 (Pin 2): Dimming and Shutdown Pin. Connect
CTRL1 below 50mV to disable converter 1. As the pin volt-
age is ramped from 0V to 1.5V, the LED current ramps from
0 to (I LED1 = 200mV/R SENSE1 ). The CTRL1 pin must not
be left ?oating.
GND (Pin 3): Connect the GND pin to the PCB system
ground plane.
CTRL2 (Pin 4): Dimming and Shutdown Pin. Connect
CTRL2 below 50mV to disable converter 2. As the pin volt-
age is ramped from 0V to 1.5V, the LED current ramps from
0 to (I LED2 = 200mV/R SENSE2 ). The CTRL2 pin must not
be left ?oating.
LED2 (Pin 5): Connection point for the anode of the ?rst
LED of the second set of LEDs and the sense resistor
(R SENSE2 ). The LED current can be programmed by:
V IN (Pin 8): Input Supply Pin. This pin must be locally
bypassed.
SW1 (Pin 9): Switch Pin. Minimize trace area at this pin
to minimize EMI. Connect the inductor at this pin.
CAP1 (Pin 10): Output of Converter 1. This pin is connected
to the cathode of internal Schottky diode 1. Connect the
output capacitor to this pin and the sense resistor (R SENSE1 )
from this pin to LED1 pin.
Exposed Pad (Pin 11): Ground. Must be soldered to
PCB.
I LED 2 =
