XL6001 including output LED open faults

Introduction
The document describes a high efficiency LED driver designed to drive an LED driver at a current of 320
mA from an input voltage range of 3.6 VDC to 20 VDC, output support 2~8 series 1W LED.
The XL6001 also provides a sophisticated range of protection features including output LED open faults
and soft-start function. Accurate hysteretic thermal shutdown ensures safe average PCB temperatures under
all conditions. Design with very low parts count.
This document contains the converter specification, schematic, PCB diagram, bill of materials.
