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

Summary
Thermal design of electronic components and systems is to ensure that the temperature rise caused by the losses remains within acceptable limits. Thermal modeling and simulation have become essential parts in process design. These integrated components are essentially magnetic components. Modeling these components provide good study of investigation of the temperature evolution through the integrated component. Modeling magnetic components requires knowledge of electromagnetic losses. Due to the complexity of determining these losses, many approaches are used to investigate the temperature evolution inside the integrated component. We propose compact thermal model that can be integrated into mathematical tools to achieve temperature distribution across the integrated LC component. In order to verify the results of the thermal resistance network approach, it is compared to thermal Finite Element Method simulation
