LTspice is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. Our enhancements to Spice have made simulating switching regulators extremely fast compared to normal Spice simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. Included in this download are Spice, Macro Models, over 200 op amp models, as well as resistors, transistors and MOSFET models. This video provides an overview of the advantages of using LTspiceIV in an analog design. Topics include the benefits of using LTspice, how easy it is to get started and where to go to download LTspice.
