There is no specific category/subcategory for DC/DC Converters in MIL-HDBK-217F, Notice 2. DC/DC Converters are often supplied as packaged devices that contain a number of components including inductors, transformers, capacitors, diodes and ICs. In order to perform a MIL-HDBK-217 reliability prediction on such a device, you would need to have information about the components used therein and model them separately. Since this information is often not available, or perhaps may even be proprietary, a better approach would be to consult the manufacturer’s data sheets or contact the manufacturer directly.
