Pin Function

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

BST and LX.

Ground.

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.

PWM dimming pin. This pin is active high.

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

threshold the device starts up.

PWM output connection to inductor.
