The library provides LTspice models for products including the flyback transformer product group, PoE and PoE+ products, offline power solutions, isolated DC-DC converters, and power supply ...

Sadly, LTSpice development seems to have stalled some years ago, but luckily for us [Mike] has been busy on the successor, QSpice, under the watchful eye of Qorvo.

Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also… ...

The LTspice implementation is shown in Figure 12. The example allows you to specify R, L, and C, or alternatively you can specify the damping factor ζ and resonant frequency ωn. 12.
