Description

Function

1

BST

Bootstrap pin. Connect a 10nF capacitor from this pin to SW.

2

GND

Ground Pin

3

FB

Feedback Input. Connect the LED string between OUTPUT

node and this FB pin, and a resistor which is used to define

the LED current from this FB pin to GND. The LED current is

set by 0.155V divided by this resistor.

4

EN

Enable pin for the IC. Drive this pin high to enable the part,

low to disable.

5

IN

Supply Voltage. Bypass with a 10μF ceramic capacitor to

GND.

6

SW

Inductor Connection. Connect an inductor Between SW and

the regulator output.
