Abstract
An integrated 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 FET. 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 driver integrated circuit (IC) paddle configured to support a driver IC for controlling each of the control FETs and each of the sync FETs. 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 FET and the second sync FET via a second clip, respectively.
