FUNCTION
Current-Regulated Output. Connect pin 1 to pin 20.
Input Supply. Bypass IN with a 0.1μF (min) capacitor to GND. Connect pin 2 to pin 3.
No Connection. Leave unconnected (internal connection).
Ground
+5V Regulated Output. Connect a 0.1μF capacitor from V5 to GND.
Positive Input of the Internal Differential Amplifier. Connect the current-sense resistor between CS+
and CS- to program the output current level.
Negative Input of the Internal Differential Amplifier. Connect the current-sense resistor between
CS- and CS+ to program the output current level.
Dimming Input. See the Dimming Input (DIM) section.
Enable Input. Drive EN high to enable the output and the 5V LDO.
Exposed Pad. Connect to the ground plane for effective power dissipation. Do not use as the only
ground connection.
