Comparison of the Total Ionizing Dose Sensitivity of a System in Package Point of Load Converter Using Both Component- and System-Level Test Approaches

Testing at system level is evaluated by measuring the sensitivity of point-of-load (PoL) converter parameters, submitted to total ionizing dose (TID) irradiations, both and component levels. shows that complete can be fully functional TID more than two times higher qualification obtained using a standard-based component-level approach. Analysis failure processes tolerance during testing increased due internal compensation in system. Finally, advantages shortcomings are discussed.
