I was just looking at these funny parts: https://www.vicorpower.com/products?productType=cfg&productKey=VTM48EF012T130C01 https://www.vicorpower.com/products?productType=cfg&productK... 130A, 48V -> 1.2V @ 94% efficiency! Except: - $100 ea. - Fixed 1/40 voltage ratio, regulation done by upstream regulator. - Look at the minimum specs for efficiency…

This is a very strange part, what with the upstream regulator circuit. My guess is that their efficiency stats dont include losses in the upstream regulator. 100 usd per unit doesnt seem that excessive.
