摘要：

In　this　paper,　the　reliability　method　and　model　of　CETRM　(Constant　Electrical　stress　and　Temperature　Ramp　stress　Method)　is　introduced　in　detail.　Based　on　the　degenerate　graph　of　input　current,　output　current　and　output　voltage　in　DC/DC　converter,　the　reliability　life　method　is　researched　and　the　life　in　the　normal　working　conditions　which　was　reckoned　is　about　8.7　×　10　4　h.　In　accordance　with　the　degenerate　graph,　the　failure　sensitive　parameter　is　output　voltage.　Then　the　failure　mechanism　consistent　temperature　range　is　75°C~160°C　by　the　failure　mechanism　consistent　model.　The　failure　activation　energies　calculated　in　this　temperature　range　is　0.59eV.　And　finally,　the　life　in　the　normal　working　conditions　is　worked　out.　It　proves　that　the　CETRM　can　be　applied　in　the　quantitative　evaluation　of　the　reliability　in　DC/DC　converter.
