100W-600W non-isolated buck converter
Hi PI,
I am looking at a fairly simple power conditioning application. I am currently implementing an offline buck. The buck must step-down the power to <36VDC, 100W max (for now).
I have gone through your tools and product lines and am seeing most solutions achieved via an isolated flyback topology (At least in the examples). Are there any quick references for one of your product lines (TopSwitch for example) or an option in PI Expert that will not transform? I am limited on real-estate and isolation is already achieved downsteam from this circuit, so it is necessary to replace the transformer with an inductor.
Thank you,
Nick

If PI expert and your documentation does not have this information, is there a reason for it? It looks like many of your families should support this, it's just not explicitly stated. I imagine a family like the HiperPFS could buck down to around 30V with a little bit of noise. Are there any FAEs available?
We never Implemented 100W Buck Converter using our Products. However top Switch can Support the Buck Converter.

Unfortunately, we do not have a non-isolated buck design based on your specifications.
