Abstract
A power supply module () comprising a metal leadframe with a pad () and a first metal clip () including a plate (), an extension () and a ridge (); the plate and extension are spaced from the leadframe pad, and the ridge connected to an input supply. A synchronous Buck converter is in the space between the clip plate and the leadframe pad, the converter including a control FET die () soldered onto a sync FET die (), the clip plate soldered to the control die having an input inductance (), and the sync die soldered to the leadframe pad having an output capacitance. A capacitor () integrated into the space between the clip extension and the leadframe pad, the clip extension soldered to the capacitor having a desired integrated inductance () operable to channel electrical energy from the switch node to ground.
