The paper concerns the problem of modelling switching voltage regulators from the L4970 family in SPICE with the phenomenon of self‐heating taken into account. The way of formulating the electrothermal macromodel of this class of circuits and its form are presented. The correctness of the formulated macromodel is verified experimentally on the example of the regulator L4975 operating in the switching stabilizer with the buck converter.
