Power quad flat no-lead (PQFN) semiconductor package with leadframe islands for multi-phase power inverter

摘要

According to an exemplary implementation, a power quad flat no-lead (PQFN) package includes a U-phase output node situated on a first leadframe island of a leadframe, a V-phase output node situated on a second leadframe island of said leadframe, and a W-phase output node situated on a W-phase die pad of said leadframe. The first leadframe island can be on a first leadframe strip of the leadframe, where the first leadframe strip is connected to a U-phase die pad of the leadframe. The second leadframe island can be on a second leadframe strip of the leadframe, where the second leadframe strip is connected to a V-phase die pad of the leadframe. A first W-phase power switch is situated on the W-phase die pad. Furthermore, at least one wirebond is connected to the W-phase die pad and to a source of a second W-phase power switch. The W-phase die pad can be a W-phase output terminal of the PQFN package.
