Switch. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.

Ground. Connect directly to local ground plane.

Feedback. Reference voltage is 95mV. Connect cathode of lowest LED and resistor

here. Calculate resistor value according to the formula: RFB = 95mV/ILED

Shutdown. Connect to 1.5V or higher to enable device; 0.4V or less to disable device.

Input Supply Pin. Must be locally bypassed.
