72 to 12 volt 40 Amp DC DC Buck Converter

Hi all,
I need 72 volt to 12 volt 40 amp DC DC Step Down converter, I searched suitable component, but I don’t find component for this duty. Could you help me for this topic.
Thanks in advance.

I’m not clear on if you are looking to design your own supply for this on a PCB or if you are looking for an external power supply. 72V input is rather high, and 40A output is quite a bit, but we do have some external power supplies that meet those requirements.

This would just barely meet your requirements:


If you want some margin for input voltage and output current, the next closest thing Digi-Key stocks is:


Dear Alec
Thank you for your effort. I see this products, This power supply suitable for me.
Best regards.
