An instance shows reachable switching frequency and power densities for planar magnetics. A condition for this is a high efficiency because at the same power loss a smaller component has a higher increasing of temperature. Realizeable efficiencies range from 98% up to 99,3 %.
The instance base on following quantities:
P : 150 W Uin : 42 V
f : 1000 kHz Uout : 5 V
Hight : 11,7 mm
Length : 26 mm
Width : 23 mm
Powerlosses : 1,8 W
