The problem of modelling a class of monolithic PWM switched voltage regulators including the bipolar output stage with the use of SPICE is considered in this paper. The STMicroelectronics regulator L296 dedicated for switched-mode power supplies based on the BUCK converter has been chosen for detailed investigations. A new large-signal electrothermal macromodel of this regulator for SPICE is presented. The correctness of the proposed macromodel has been verified experimentally.

W pracy rozważany jest problem modelowania w programie SPICE monolitycznych regulatorów impulsowych realizujących sterowanie PWM i zawierających bipolarny stopień wyjściowy. Szczegółowe rozważania przeprowadzono na przykładzie regulatora L296, produkowanego przez STMicroelectronics i przeznaczonego do pracy w zasilaczach impulsowych z przetwornicą BUCK. Przedstawiono nowy wielkosygnałowy elektrotermiczny makromodel rozważanego regulatora dla programu SPICE. Dokładność zaproponowanego makromodelu zweryfikowano doświadczalnie.
