Enable and input peak current control pin.
This pin is pulled up to 4.5V internally to set V
external MOSFET shuts down. If 0.5
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.
