Functions
Switch Pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.
GND pin.
Feedback Pin. Reference voltage is 0.1V. Connect cathode of lowest LED and a sense resister here. Calculate resistor value
according to the formula: R SET = 0.1V / ILED
Converter On/Off Control Input. A high input at EN turns the converter On, and a low input turns it off. If On/Off control is not
needed, connect EN to the input source for automatic startup. The EN pin cannot be left floating.
Output Voltage detect pin for over voltage protection.
Input Supply Pin. Must be locally bypassed with 1 μ F or 2.2 μ F to reduce input noise.

Caution:
Operation above the absolute maximum ratings can cause device failure. These values, therefore, must not be exceeded under any condition.
Operation at the absolute maximum rating for extended periods, may reduce device reliability.
