/diy/ - Do It Yourself

We're not your personal datasheet googlers, and this isn't some sort of headphone recommendation thread. If you want us to provide useful information the least you could do is be polite about it.

Second google result for "lipo 3.3V converter":
https://www.pololu.com/product/2122/specs
looks pretty decent if you want a PCB to solder onto. I think that's a fairly reputable site.

On Ali searching "buck boost 3.3V converter" I get this:
https://www.aliexpress.com/item/personalarmy/32963598972.html
after sifting through some results that are distinctly boost or buck only.

Then a parametric search on digikey:
>min input voltage = 3V - 0V
>max input voltage = 4.8V - 100V
>max current output = 300mA - 32A
>voltage output = 3.3V
Gives me a fuckton of obscure SMT components like pic related and some high-power THT stuff, so probably not actually that useful to you. Perhaps Octopart would cater better to this sort of thing.
