Notes
Why it is interesting: a complete, enclosed PSU rather than an open-frame stage, and the efficiency is quoted both with and without the fan, which is rare. It is a good benchmark for honest density numbers: 1.95 kW/L including the enclosure.
Watch out: vin.max = 230 V is the efficiency test point; the full input range is in the user guide. The URL follows Infineon’s usual pattern but was not opened directly; the link check will confirm it.
