The problem of modelling a class of monolithic integrated circuits with the use of SPICE is considered in this paper. The STMicroelectronics regulator L296 dedicated for switching-mode power supplies based on the BUCK converter has been chosen for investigations. A new large signal electrothermal macromodel of the L296 for SPICE is presented. This macromodel is formulated in the network form with the use of controlled sources accessible in SPICE. The correctness of the proposed macromodel has been verified experimentally.
