No Connection. Leave unconnected (internal connection).
5V Regulated Output. Connect a 0.1μF capacitor from V5 to GND. Connect pin
12 to 15.
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 regulator.
Momentary Switch Interface. See the Momentary Switch Interface (SW) section.
Thermal Foldback Positive Input/I 2 C Serial Clock Input. See the Thermal Sensor
Inputs/I 2 C Interface (TFP/SCL and TFN/SDA) section.
Thermal Foldback Negative Input/I 2 C Serial-Data Input/Output. See the Thermal
Sensor Inputs/I 2 C Interface (TFP/SCL and TFN/SDA) section.
Exposed Pad. Connect to the ground plane for improved power dissipation. Do
not use as a ground connection for the part.
