Zusammenfassung:Apparatuses and methods directed to a semiconductor chip package having multiple leadframes are disclosed. Packages can include a first leadframe having a die attach pad and a first plurality of electrical leads, a second leadframe that is generally parallel to the first leadframe and having a second plurality of electrical leads, and a plurality of direct electrical connectors between the first and second leadframes, where such direct electrical connectors control the distance between the leadframes. Additional device components can include a primary die, an encapsulant, a secondary die, an inductor and/or a capacitor. The plurality of direct electrical connectors can comprise polymer balls having solder disposed thereabout. Alternatively, the direct electrical connectors can comprise metal tabs that extend from one leadframe to the other. The first and second leadframes can be substantially stacked atop one another, and one or both leadframes can be leadless leadframes.
