Pin Function

1

BST

Bootstrap voltage input. High side driver supply. Connected to 10 nF capacitor between

BST and LX.

2

GND

Ground.

3

FB

LED current feedback. The FB pin regulation voltage is 280 mV. Connect an external

sense resistor between the cathode of the LED string and GND to set LED current.

4

DIM

PWM dimming pin. This pin is active high.

5

VIN

Supply voltage input. Input range from 3 V to 26 V. When VIN rises above the UVLO

threshold the device starts up.

6

LX

PWM output connection to inductor.
