Okay, the IR2011 is working great, I asked analogspiceman how to properly insert into the schematic and here's how:

Zitat:The IR2011 .asc and .asy files are the only components needed for the
hierarchical model to work in your schematic. They simply need to be located in the same folder as where your schematic was opened. The tricky
part, if you haven't done it before, is placing a hierarchical symbol for the first time. Voilà:

1) From within the LTspice schematic editor, open the "Place Component Symbol" dialog box as usual.

2) At the very top of the box click on the down arrow to get the drop-down selection pick list for a new "Top Directory".

3) Choose the folder where your working schematic currently is located and the IR2011 should now appear in the symbol selection area.

4) Select it and place it on your schematic as usual.

If desired, you may open the sub schematic (of the IR2011) by right clicking on it from within the top level schematic (your class d design).
In this way you can access internal driver nodes during a simulation and plot them with a simple point-and-click (be sure you've enabled save subcircuit node voltages/currents from within the "Save Defaults" tab of the Control Panel).

Good luck! -- analogspiceman
