2.5 QFN-FCMOD

The leaded module packages include a dual copper leadframe with a power IC in between the leadframes. The integrated inductor, capacitor, and any other passives are situated on the top leadframe. There is molding compound encapsulating the package. There are leads and a large GND pad for good heat transfer and easy layout. provides an illustration of this package construction.
