Abstract
Abstract A surface mount package for containing a board-mounted power supply, a method of manufacturing the same and a board-mounted power supply employing the package. In one embodiment, the package includes: (1) a plurality of leads having first ends and second, surface mount ends, (2) a dielectric lead frame that retains the plurality of leads in predetermined positions relative to one another such that at least some of the second, surface mount ends are co-planar, the first ends couplable to the board-mounted power supply, (3) a shell, coupled to the lead frame, that forms a portion of a periphery of the surface mount package and (4) potting material located between the lead frame and the shell.
