I saw voltage on it and was curious with that. With being able to adjust think it will see any eficiency change?
Or mainly just a fix and that's it.
No it's just a rather complicated and expensive way of repairing your 12V to 14V step up converter, by completely replacing all of the circuitry. Not a lot of value in the adjustable voltage as it needs to be set a couple of volts over the supply voltage in order that the LDO Regulators will function.

so is this some possiblity to fix burned boards by doing this?. seems that u101 chip is mostly the failure. and you cant purchase a loose chip .
Yes although their add does not say as much I see is being an "easy" way to repair your 14V upconverter that supplies the LDO's in the top 3 stages in the chain. How often U101 or other parts of that circuitry fail I do not know?

looks like the piece?.
i've been researching seem slike a common failure when short circuit the board,and u101 chip seems impossible to get.
