Your rating: not submitted

LTspice IV is an advanced and high performance application that can be used as a schematic capture, waveform viewer and SPICE simulator, providing models and enrichment for making the simulation easier. Compared to other SPICE simulators, this application makes simulating switching regulators very fast and lets you quickly view waveforms for the majority of switching regulators in a matter of minutes.

In the provided package you will found a set of Macro Models for a wide range (about 80%) of Linear Technology's switching regulators, the LTspice IV application, more than 200 op amp models, as well as transistors, resistors, and MOSFET models.


  • Provides a wide range of models for simulation and switching regulators.
  • Allows you to quickly view waveforms for the majority of switching regulators.


  • The application requires some technical skills in electronics.
  • The program provides models only for Linear Tech components.
