Welcome to adventures with analog!

Let me begin by thanking Linear Technology and Mike Engelhardt,
the author of LTspice, for providing the worldwide electrical
engineering community with such a highly functional and well
supported design tool.

Before using any of my models I would suggest taking a quick
look at the files: "Waveform_Arithmetic_&_B-sources" and
"LTspice_Hot_Keys". The former explains several useful
functions and features that were somehow omitted from the help
file, including the "Freq" syntax of behavioral sources. It
also clarifies which waveform arithmetic functions work with
only real or imaginary arguments and lists many previously
undocumented internal constants such as an electron's charge,
the speed of light and the temperature of absolute zero.

Clearly, in the hands of the development team at Linear
Technology, LTspice is quite capable of adeptly modeling very
complex power supply control ICs. The models you'll find in
this folder are the work of a team of one and, as such, may
not be as thoroughly debugged as those from Linear Technology.

My models are generally developed in schematic format and are
intended to be used via their accompanying symbol file as
hierarchical objects within higher level schematics. This is
a very powerful and easy to use feature of LTspice that is
worth the small effort required to learn (just place a copy
of the hierarchical model's symbol and schematic files in the
same directory as the top level design and use the drop-down
Top Directory menu to get to the model via the component
button on the tool bar).

Index of models to be uploaded:

UC384X series of single output PWM control ICs.
UCC38083 (dual output PWM control IC - requires SwitchYard).
IR21064 (half bridge driver).
TL431A (shunt regulator - very difficult to simulate well).
V320LA40B (varistor).
An NTC inrush current limiter (with temperature output).
A simple photovoltaic panel model.
One and two pole generic op amp models with reasonable BW,
slew rate limiting, voltage and current limiting, PSRR,
noise and power draw from the power supplies (these models
will work with "floating" power supplies).
A neon light bulb model.
An incandescent light bulb model.
A basic LISN model.
Techniques for simulating conducted EMI.
Methods for simulating realistic transformers.
Methods for generating average models of switching circuits.
Some example switch mode power supplies.
Some interesting class d amplifier stuff along with a bass
loudspeaker model.

+Q: I am struggling to understand the simulation results in ChanCore.asc reference design. Thanks for making this available analogspiceman. Don't want to sound like I am complaining. Very nice of you to offer your work to others.
