The paper states the concept of a very high power density flyback converter. Due to its less complex schematic flyback converters are recommended for power supplies providing low output power with inputs from low level DC voltages to high DC voltages (off-line SMPS). Main innovations are used: planar magnetics-PCB transformer and proprietary special packaging. As a result the parasitic are highly reduced and the almost ideal DC-DC converter, of 25 W, 12 V input to 48 V output reaches a power density of 100 W/inch3
