By using high efficiency ferrite cores suitable for power conversion with very low power loss and large magnetic flux density it is possible to design transformers that is quite compact in size and high efficiency.
A wide variety of shapes and sizes from low output to high output power, gives great flexibility of design switching power supply.
Bobbins and other components are also available which are capable for a variety of safety regulations such as UL, CSA and VD.
