Switch Pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.
Common Ground
GND
Feedback Pin. Reference voltage is 0.25V. Connect cathode of lowest LED and resistor
here. Calculate resistor value according to the formula: RFB=0.25/ILED
Chip Enable Pin. Connect to 1.4V or higher to enable device, 0.3V or less to disable
device.

Input Supply Voltage
Overvoltage Sense. When VOUT is greater than 27V, the internal N-channel MOSFET turns
off until VOUT drops below 25V, then the IC reenters start. Connect a 1uF capacitor from
OUT to GND.
