DC-DC converter vertically integrated with load inductor structured as heat sink

摘要

A power supply converter (100) comprising a first FET (210) connected to ground (230), the first FET coupled to a second FET (220) tied to an input terminal (240), both FETs conductively attached side-by-side to a first surface of a metal carrier (120) and operating as a converter generating heat; and a packaged load inductor (110) tied to the carrier and an output terminal (241), the inductor package wrapped by a metal sleeve (113) in touch with the opposite surface of the metal carrier, the sleeve operable to spread and radiate the heat generated by the converter.

1. A power supply converter comprising:
a first FET, a second FET, a metal carrier, and a load inductor; the first FET connected to ground and coupled to the second FET tied to an input terminal, both FETs conductively attached side-by-side to the metal carrier and operating as a converter generating heat; and the load inductor tied to the metal carrier and an output terminal, and wrapped by a metal sleeve in touch with the carrier opposite to the FETs, the sleeve operable to spread and radiate the heat generated by the converter.
