Pin Function
Gate Driver Output for External MOSFET Switch in the First Stage.
Current Sense Input for External MOSFET Switch.
Over Voltage Protection Sense Input.
Ground. The exposed pad must be soldered to a large PCB and
connected to GND for maximum power dissipation.
LED Current Sense Amplifier Negative Input.
Supply Voltage Input. For good bypass, place a ceramic capacitor
near the VCC pin.
Internal Regulator Output. Place an 1μF capacitor between the
CREG and GND pins.
Gate Driver Output for External MOSFET Switch in the Second
Stage.
