Introduction :
The document describes a high efficiency LED driver desi gned to drive an LED driver at a current of 320
mA from an input voltage range of 5 VDC to 32 VDC, output support 2~16 series 1W LED.
The XL6005 also provides a sophisticated range of protection features including output LED open faults
and soft-start functi on. Accurate hysteretic thermal shutdown en sures safe average PCB temperatures under
all conditions. Design with very low parts count.
This document contains the converter specification, schematic, PCB diagram, conducted EMI
measurements, bill of materials and tical performance characteristics.
