Abstract

In this paper the problem of modelling selfheating influence on the characteristics of monolithic switch-mode power supplies is considered. The LT1073 integrated circuit (IC) has been chosen for detailed investigations. Its new ElectroThermal Macromodel (ETM) joining the Electrical Model (EM) along with the thermally dependent parameters and the Lumped Thermal Model (LTM) generating the junction (inner) temperature of LT1073 is proposed. The correctness and usefulness of the new model has been revealed by means of comparison of measurements and simulations of BOOST converter including LT1073 device.
