LTspice Demo Circuits

LTspice IV is a powerful, fast and free simulation tool, schematic capture and waveform viewer with enhancements and models for improving the simulation of switching regulators. LTspice provides macro models for most of Linear Technology’s switch-mode DC/DC converters, op amps, comparators, linear regulators as well as a library of devices for general analog circuit simulation including discretes. Selected Linear Technology devices also have demonstration circuit available for free download. These demo circuits are designed to ensure proper performance and have been reviewed by Linear Technology’s factory applications group. Follow the instructions below to run the demo circuits in LTspice.

• Step 1. If you do not already have a copy of LTspice, click here to download and install LTspice.
• Step 2. Once LTspice is installed,  click on the link(s) below to launch the simulation.  LTspice should open automatically.
• Step 3. If LTspice does not automatically open after clicking the above link, you can instead run the simulation by right clicking on the link and selecting “Save Target As”. After saving the file to your computer, start LTspice and open the demonstartion circuit by selecting "Open" from the "File" menu.
