5.7 Design Example – Regulate Board and Case Temperature to Maintain Safe Operation

In the previous example we showed how given the PCB and case temperature, the current of the power block could be limited to ensure operation within the SOA. Conversely, if the current and other application conditions are known, one can determine from the SOA what board or case temperature the user will need to limit their design to. The user can estimate product loss and SOA boundaries by arithmetic means. Though the power loss and SOA curves in this data sheet are taken for a specific set of test conditions, the following procedure outlines the steps the user should take to predict product performance for any set of system conditions.
