摘要： Provided are a transformer, capable of simplifying a manufacturing process and enhancing heat dissipation characteristics and insulating characteristics by adopting a dual-bobbin structure and configuring a secondary winding as a metallic plate extending to the outside, and an electronic device including the same. Heat dissipation from a primary winding is facilitated by forming a primary winding at the outer side. Furthermore, a secondary metallic plate, although formed inside, includes extension portions to thereby facilitate heat dissipation from the secondary metallic plate. Also, by adopting a dual bobbin structure for outer and inner bobbins, a sufficient distance for insulation between the primary winding and the secondary metallic plate is ensured to thereby enhance an insulating function. Further, a manufacturing process can be simplified by forming a secondary winding as a metallic plate manufactured in advance.

摘要： Provided is a flyback DC/DC converter for a power supply. In the flyback DC/DC converter, a flyback driver unit provides a primary current. A transformer includes a plurality of secondary coils for inducing energy from the primary coil receiving the primary current. A rectifier unit includes a plurality of rectifier diodes for rectifying secondary currents of the corresponding secondary coils of the transformer. A plurality of clamp diodes are connected in series to the corresponding rectifier diodes of the rectifier unit in a forward direction to clamp ringing voltage across the corresponding rectifier diodes when the power switch is turned off. Accordingly, the voltage across the rectifier diode on the secondary side can be reduced such that it is lower than the output voltage.
