摘要:
An encapsulated buck converter module includes a low side transistor and a control integrated circuit bonded to a first section on a first side of a leadframe, a first clip between a source of the low side transistor and a second section, a source contact of a high side transistor attached to the first section on a second side of the leadframe with a gate contact of the high side transistor attached to a third section, a conductive member attached to the first and second sections on the second side of the leadframe wherein the first side of the conductive member attached to the second conductive member forms a conductive path with a portion of a second side of the conductive member while any portion of the first side of the conductive member attached to the first component attachment section is insulated from the first side of the conductive member, a first plate of a capacitor attached to a drain contact of the high side transistor and a second plate of the capacitor attached to the second side of the conductive member, and means for forming an external connection to the drain contact of the high side transistor.
