Abstract:
1. A method for fabricating a power supply converter, comprising: providing a load inductor wrapped by a metal sleeve structured to transform the inductor into a heat sink; positioning the inductor to deposit layers of solder paste on a sleeve surface and on the inductor leads; providing a metal carrier having a portion of a first thickness and portions of a greater second thickness; placing the carrier on the solder layers of the inductor wherein the carrier portion of first thickness is aligned with the inductor sleeve and the carrier portions of second thickness are aligned with the inductor leads; placing a sync and a control FET side-by-side on solder layers deposited on the carrier portion of first thickness opposite the inductor sleeve; and reflowing and then solidifying the solder layers, whereby the FETs, the carrier and the inductor become integrated and the un-soldered surfaces of the FETs and the carrier portions of second thickness become coplanar.
