I beleive the En jumper and the solder pad enable you to use the regulator without feedback from the load- Kelvin sense. I use mine with the jumper.

The green line lets you link two boards and common the output of both for current sharing duties.

I have one, it works well on modest current's but I need a solution for heatsinking it at 12v/12.2v and 1 amp. Think i'm going to use a heat spreader on the underside.
