Usual approach is to go higher not lower, in specs.
Then again, it all depends on the application, which is not shown.
Best advise under those conditions, suck it and see....2cent part.
Don't know why you arrive at this conclusion..............which way is "backwards"..??
At that time one is assuming "the problem" is not known for one thing.
Doesn't make any sense.
Breadboards and "smoke alarm" batteries were never made for high current circuits.
Those thin as hookup wire either BTW....or tactile switches.........:oops:
Can you supply the data sheet you refer to and a wiring diagram of your setup.
We do not have a need to go searching all over for it or second guessing how you want to connect everything.
For the last time, your problem is the voltage conversion which is a right pia costly process and not worth the effort.
The frequency change won't be a problem compared to the former.
If nothing else faulty caused it to blow it's top in the first place............
You may also (more than likely) find it difficult and damaging to the pcb to unsolder without the proper tools.
Startout tip would be to flood the pins with a good flux and some 60/40 solder then remove with a good...
Don't have the time or the need to study the differences....at any rate, it would be safe to say it will make zero difference to you currently anyhow...just being realistic.
Let us know what you find...that's normally how it works my end at least.
