LTspice IV
Author : Linear
Licence Type : Freeware
Size : 15.3 MB
Hits : 12748
Description : LTspice IV is a high performance SPICE 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 LTspice IV, Macro Models for 800f Linear Technology's switching regulators, over 200 op amp models, as well as resistors, transistors and MOSFET models.
