This design is a current limiter based on a LED driver. It can be used for various applications and changed easily to a different current limit. PMP8531 uses LM3409 buck controller. An excel spreadsheet shows two different configurations (current source or eletrical fuse) and helps the designer to quickly achieve a working design.
