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 …
