Slope compensation setting. A resistor between the output of the boost
converter and this pin is needed to avoid sub-harmonic instability.

Power ground. Source of the internal power-MOSFET.
Over-voltage selection. Used to set the desired OV threshold by an external
divider. See
Switching node. Drain of the internal power-MOSFET.
Dimming input. Used to externally set the brightness of the LEDs by using a
PWM signal.
Enable input. When low, the device is turned off. If tied high or left floating,
the device is turned on and a soft-start sequence takes place.
Fault signal output. Open drain output. The pin goes low when a fault
condition is detected (see
Synchronization output. Used as external synchronization output.
Soft-start. Connect a capacitor to SGND to set the desired soft-start
duration.
