The transient thermal impedance Z(t) of the monolithic switched regulator LT1073 is investigated in the paper. A new method of measuring this thermal parameter of the device in its real operation conditions is proposed and the proper measuring set is described, too. The results of the Z(t) measurements of the device operating at it various cooling conditions are presented. Apart of this, the measuring results corresponding to the steady-state obtained both by the proposed method and by the other known methods are compared.
