If you ever worked with the MC34063 Switching Controller, you know what a pain it is to calculate all the part values. This tool is an universal tool to help you with this process. You can calculate any standard application, such as step-up, step-down, inverting and step-up-down.
PS: I would be happy about any (positive xD) reviews as well as any bugreports, comments or feature requests that you might have!
