Thermal behavior of integrated passive components has become an important\nissue when designing these components. This paper presents the thermal\nmodeling of a multilayer integrated LC filter used in DC-DC step-down converter\nfor temperature distribution calculation. The approach used for this\nanalysis is based on thermal equivalent circuit. Temperature distribution is\nobtained from algebraic equation, which is in vector and matrix form. The\nresults of analytical calculation are compared with simulation results from finite\nelement method. These results showed a good correlation.
