FUNCTION
Control Logic Input (see Table 1)
2
CP
Transfer Capacitor Positive Connection. Connect a 1μF capacitor (or 2.2μF for I
OUT
> 600mA) from
CP to CN.
3
CN
Transfer Capacitor Negative Connection. Connect a 1μF capacitor (or 2.2μF for I
OUT
> 600mA) from
CP to CN.

GND
Control Logic Input (see Table 1)
Ground
6
IN
Input Supply Voltage. Connect IN to a battery or supply voltage from 2.7V to 5.5V. Connect a 4.7μF
ceramic capacitor from IN to GND.
7
CS
Current-Sense Input. Connect a current-sense resistor from OUT to CS to set the output current.
Connect the anodes of the LEDs to CS and the cathodes to GND.
8
OUT
Output. Connect a 10μF ceramic capacitor from OUT to GND. In shutdown, OUT is pulled to GND
with an internal 5k
resistor.
Exposed Pad. Connect the exposed pad to GND directly under the IC.
