FB

Feedback Reference Voltage Pin. Series connect a resistor between WLED and

ground as a current sense. Sense the current feedback voltage to set the current

rating.

EN

Chip Enable (Active High). Voltage sensing input to trigger the function of over

voltage protection. Note that this pin is high impedance. There should be a pull low

100kΩ resistor connected to GND when the control signal is floating.
