发明名称 Power Converter Having Integrated Capacitor
摘要 A power supply module (400) comprising a metal leadframe with a pad (401) and a first metal clip (440) including a plate (440a), an extension (440b) and a ridge (440c); 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 (410) soldered onto a sync FET die (420), the clip plate soldered to the control die having an input inductance (462), and the sync die soldered to the leadframe pad having an output capacitance. A capacitor (480a, 480b) integrated into the space between the clip extension and the leadframe pad, the clip extension soldered to the capacitor having a desired integrated inductance (463) operable to channel electrical energy from the switch node to ground.
