As of January 31, 2020, TI.com will no longer support Flash-based tools, such as SwitcherPro, and will end-of-life (EOL) or replace them with an HTML-based version. Prior to January 31, 2020, please download any needed projects from the tools. To find alternative tools, and to see the full list of impacted tools, please see this post on the TI e2e™ support forums.
The recommended replacement for the SwitcherPro is the WEBENCH Power Designer. Please use this tool going forward.
