Patent ID: 8023279

Claim:
An encapsulated buck converter module with an integral capacitor comprising: a) a low side transistor and a control integrated circuit bonded to a first component attachment section on a first side of a leadframe; b) a first clip between a source of said low side transistor and a second component attachment section; c) a source contact of a high side transistor attached to said first component attachment section on a second side of said leadframe with a gate contact of said high side transistor attached to a third component attachment section; d) a conductive member attached to said first component attachment section and said second component attachment section on said second side of said leadframe wherein said first side of said conductive member attached to said second conductive member forms a highly conductive path with a portion of a second side of said conductive member while any portion of said first side of said conductive member attached to said first component attachment section is insulated from said first side of said conductive member; e) a first plate of a capacitor attached to a drain contact of said high side transistor and a second plate of said capacitor attached to said second side of said conductive member; and f) means for forming an external connection to said drain contact of said high side transistor.
