Replacing Enspirion DC/DC converters

We are currently using two Enspirion DC/DC converters that we need to replace.

The EN2342QI (12V in, 1.8 - 3.3V out, 4A) we think we can easily replace with the MPM3650C

But for the EN23F2QI (15A, 12V in, 1.1V out) we would need a chip (or two in parallel) that fits within 11.9 x 10.9mm, has a max. height of 3mm (ideal would be less, so we could use a piggyback attempt).

Do you have chips that fit our space requirements and that can output at least 12A (multiple chips parallel is fine too), best with a height of less 2.2mm. 3mm Would also work as a maximum height, but would make testing harder as we couldn’t use a piggyback board.

Hello Patrick,
Welcome to the forum.
The nearest chip to replace EN23F2QI is MPM3695-10 with the desired dimensions. But, the maximum current it can output is 10A.

Let us know if this works.

Can this be used without using the PMBus?

Yes, It can.
