While trying to fix a laptop, I was de-soldering a TPS51125. I added a bit too much solder to the power pad while wicking so I had the "smart" idea to use a solder pump to remove it... but the pad came with it!
I've learnt a lesson but I'm wondering if this pad is really necessary for normal functioning? Can I go without it or does it need to be connected for electronic and/or thermal reasons?
If I just stick the pad back on the pcb and solder the IC back, will it not being connected do anything to affect it's ability to function?
EDIT: here's an image of the problem for interest sake
