LP55281 Powering RGB LED with External Supply instead of Boost Output

Other Parts Discussed in Thread: LP55281

The first page of the LP55281 datasheet says: "The RGB driver can drive individual color LEDs or RGB LEDs powered from boost output or external supply." 

As I already have a 5V rail in this design, powering directly from an external supply that would be best. I assume I can remove Lboost, D1, and Cout. Are there any other components which are unnecessary when using the device in this fashion? And how should SW and FB be connected?

Thanks,

Evan
