Hi
As a hobbyist, i’m working on a dc-dc buck-boost 4 switches converter (4 MFets or 2 MFets + 2 schotky diodes) abble to work with one 18650 Li-Ion better as vin (3V Vin-min, 4.2V Vin-max) and to deliver an output controled by mcu (atsamd21g18) from Vout-min 2V (2A) to Vout-max 5V (5A). The output will power a heating coil around 1 ohm.
I already designed my topologie, make temporary calculations, etc, but i can’t find any gate driver IC within these specs.
I am open to all suggestions, Intergrated IC’s or other.

I forgot to mention that for now my fets are BSC014NE2LSI, but it’s also open to discution.

Hello,

Thank you for your post.

With that information I am only able to narrow down our selection of gate drivers so far.

Here is a link to what I was able to narrow down to based on the FET you have and the supply voltage ratings.

Hi,
thank you for the answer :pray:

With that information I am only able …

do you need more informations ? what infos ?
the full project is here bachir/vbox - vbox - Gitea
the idea is to build my own diy vaping boxmod chipset.

what do you think about 2EDR7259XXUMA1 ?

thanks again :slight_smile:

By looking at the specs for the 2EDR7259XXUMA1 this should work to drive both of the BSC014NE2LSI

Thanks Craig
