Abstract
A dual power converter package is disclosed. The package includes a leadframe having a first control FET paddle configured to support a drain of a first control FET, and a second control FET paddle configured to support a drain of a second control PET. The leadframe further includes a sync FET paddle configured to support a source of a first sync FET and a source of a second sync FET, and a first plurality of contacts configured to receive control signals for each of the control PETS and each of the sync FETs from a driver integrated circuit (IC) external to the leadframe. The leadframe may additionally include first and second switched nodes, configured for electrical connection to the first control FET and the first sync FET via a first clip, and to the second control PET and the second sync PET via a second clip, respectively.
