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.
