Ground.
Driver’s output for the gate of the Q
Current sense input for the boost, peak-current control loop.
Feedback voltage input pin. Used to regulate the current of the LEDs by keeping V
Overvoltage protection input pin. If the voltage at OVP exceeds the over-voltage input threshold, V
the GATE output shuts down.
