Practical Thermal Design With DC/DC Power Modules

Texas Instruments

Published Date: 03 Oct 2018

Description

All DC/DC converters dissipate power in the form of heat. This heat has to be managed properly so that the converter maintains operation within the recommended temperature limits. Usually, the copper on the printed circuit board (PCB) is utilized to help dissipate the heat. This application note outlines a design procedure to quickly estimate the minimum required copper area on the PCB for a successful thermal design with DC/DC power modules.
