FUNCTION
Dimming Input 1. DIM1 is a low-frequency dimming input for channel 1. A logic-low turns off
OUT1 and a logic-high turns on OUT1.
Dimming Input 2. DIM2 is a low-frequency dimming input for channel 2. A logic-low turns off
OUT2 and a logic-high turns on OUT2.
Dimming Input 3. DIM3 is a low-frequency dimming input for channel 3. A logic-low turns off
OUT3 and a logic-high turns on OUT3.
Open LED Output. LEDGOOD is an open-drain output. A logic-high indicates the LED

connection is good in all three channels. A logic-low indicates an open LED connection. See the
LEDGOOD section.

Positive Input Supply. Bypass with a 0.1μF (min) capacitor to GND. Connect all IN
pins together.
LED Detection-Timing Setting. Connect a capacitor from LGC to ground to set the delay time
for LEDGOOD.
3.4V Voltage Regulator. Connect a 0.1μF capacitor from REG to GND.
Ground
Channel 3 Sense Amplifier Positive Input. Connect the current-sense resistor between CS3
and GND to program the output current level for channel 3.
Channel 2 Sense Amplifier Positive Input. Connect the current-sense resistor between CS2
and GND to program the output current level for channel 2.
Channel 1 Sense Amplifier Positive Input. Connect the current-sense resistor between CS1
and GND to program the output current level for channel 1.
Current Regulator Output 3
Current Regulator Output 2
Current Regulator Output 1
Exposed Pad. Connect EP to a large-area ground plane for effective power dissipation. Do not
use as the IC ground connection.
