Pin Description PIN NAME FUNCTION 1, 16 OUT Current-Regulated Output. Connect pin 1 to pin 16. 2, 3 IN Positive Input Supply. Bypass IN with a 0.1µF (min) capacitor to GND. Connect pin 2 to pin 3. 4–8, 14 N.C. Not Internally Connected 9 CS+ Positive Input of the Internal Differential Amplifier. Connect the current-sense resistor between CS+ and CS- to program the output current level. 10 CS- Negative Input of the Internal Differential Amplifier. Connect the current-sense resistor between CS- and CS+ to program the output current level. 11 V5 +5V Regulated Output. Connect a 0.1µF capacitor from V5 to GND. 12 GND Ground 13 DIM Pulsed Dimming Input. Drive DIM low to disable the output. Drive DIM high to enable the output. Must not be left unconnected. 15 EN Enable Input. Drive EN high to enable the output. —EP Exposed Pad. Connect to the ground plane for effective power dissipation. Do not use as the only ground connection. |
