    I have a circuit I would like to run through simulation. The circuit has some custom components that are not in the default library. I have an LED driver, voltage detector, Power Transistor, etc..

    One such component is :

    Is there location on the web that has a master component library I can search to see if someone created them already and just download them?

    Do manufacturers typically provide components for LTSpice? Seems like a standard program for circuit design/simulation...

    Can anyone point me to a good tutorial on how to create these custom components ?

    Thanks for the help...

    Hey Budman, try here:

    And try searching "add models to LT Spice" on the net; this is a big topic, lots of info on how to do it!

    You simply need to FIND the model for what you want ("LMXXX model" for ex)...when you get it, you download the .zip it will come in. There are a couple of files; they go in different folders in LT, where the others of same type are. Not hard.

    MAKING a model is more involved; I haven't had the need to yet! :)
