摘要： Generally, methods and processes for assembling magnetic components are presented herein. More specifically, conductors are wound around a substantially hollow bobbin. Portions of the conductors may be temporarily positioned outside the bobbin through slots in the flanges of the bobbin during the assembly process. Insulating layers may be wrapped around the conductors. The center legs of a pair of magnetic core halves may be inserted into the bobbin. The base of the magnetic core halves may have a passage to allow a conductor to pass therethrough at a height less than the height of the base.

摘要： A start-up circuit for a power adapter and method of operating the same. In one embodiment, the power adapter includes a start-up circuit configured to provide an initial bias voltage for the power adapter. The power adapter also includes a crowbar circuit configured to turn on the start-up circuit upon loss of an ac mains voltage supplied to the power adapter.

摘要： A controller for a power converter and method of operating the same. In one embodiment, the controller includes an inductor-inductor-capacitor (“LLC”) controller configured to receive an error signal from an error amplifier to control a switching frequency of an LLC stage of the power converter to regulate an output voltage thereof. The controller also includes a power factor correction (“PFC”) controller configured to control a bus voltage produced by a PFC stage of the power converter and provided to the LLC stage so that an average switching frequency thereof is substantially maintained at a desired switching frequency.

摘要： A burst mode controller for a power converter and method of operating the same. In one embodiment, the burst mode controller includes a burst mode initiate circuit configured to initiate a burst mode of operation when a signal representing an output voltage of the power converter crosses a first burst threshold level. The burst mode controller also includes a voltage elevate circuit configured to provide a voltage elevate signal to raise the output voltage if a time window expires before the signal representing the output voltage of the power converter crosses a second burst threshold level.

摘要： Generally, a low-profile planar core structure for use in magnetic components and related processes are presented herein. More specifically, the planar core structure provides a relatively large winding area that reduces heat dissipation, reduces leakage inductance, and allows for a low-profile design. The planar core structure has a center core that is elongated along a horizontal axis. Furthermore, conductors may enter and exit the planar core structure without increasing its height.
