Stacked half-bridge package with a common conductive leadframe

摘要

According to an exemplary embodiment, a stacked half-bridge package includes a control transistor having a control drain for connection to a high voltage input, a control source coupled to an output terminal, and a control gate for being driven by a driver IC. The stacked half-bridge package further includes a sync transistor having a sync drain for connection to the output terminal, a sync source coupled to a low voltage input, and a sync gate for being driven by the driver IC. The control and sync transistors are stacked on opposite sides of a common conductive leadframe with the common conductive leadframe electrically and mechanically coupling the control source with the sync drain. The common conductive leadframe thereby serves as the output terminal.
