Abstract
A power supply adapter is provided. The power supply adapter includes a power converter circuit configured to generate a regulated voltage signal. The power converter circuit includes a rectifier coupled with AC power blades. A regulator circuit is coupled with the rectifier. A transformer is coupled with the regulator circuit. The transformer includes a primary and a secondary. The transformer is coupled with the regulator circuit via the primary. An output circuit is coupled with the secondary of the transformer. The output circuit includes an output capacitor. A flexible contact is coupled with each of a first and a second printed circuit board and flexibly biased to couple with a proximate end of the AC power blades. The adapter includes an EMI shield substantially surrounding a connector receptacle. The power converter circuit can include a forward or a flyback power converter. The transformer can include a planar format transformer coupled with the first or the second PCB. The transformer can include a metallic core of a ferrite material. The transformer core can be coupled with the EMI shield to provide thermal spreading. The adapter can include an enclosure for housing the power converter circuit. The enclosure includes a thermally conductive potting material substantially filling an empty space of an interior of the enclosure.
