DESCRIPTION

1

SW

Switch Output. Connect this pin to the inductor and the Schottky diode.

2

G

Ground

3

OV

Over Voltage Protection Input. The IC is automatically disabled when the voltage at this pin

exceeds 1.21V. Connect OV to the center point of a resistive voltage divider connected across

the LED string.

4

FB

Feedback Input. Connect this pin to the cathode of the bottom LED, and a current feedback

resistor between this pin and G to set the LED bias current.

5

EN

Enable Control. Drive to a logic high to enable the device. Connect to a logic low to disable the

device. EN should not be left floating; connect EN to IN when unused.

6

IN

Supply Input
