For the existing regulator, I assume you are talking about this one:
Unfortunately, the main chip on that regulator got discontinued, which is the reason for the NRND status. We should still be able to make tens of thousands of units with the last of the components we ordered, which I expect to last us around a year (it’s difficult to forecast since we are trying to move people away from this product). We do not have a replacement with the same size yet, but we will be working on it in the next several months. We do have other boost regulators for 3V to 12V, but they are larger.
I will look into higher-voltage boost regulators. What kind of current do you need? If you need a modest quantity (at least a hundred units or so), we should be able to modify this regulator for a fixed 32V output:
Would that be useful to you?
