Thanks for providing a PSPICE model for the LM5050-1. The Documentation includes references to LTspice, and while the model sort of works, it throws an error:
Error on line 1002 : .model u1:lm5050-1_s1 vswitch roff=1e6 ron=1 vh=0.16 vt=1.47 td=250n
* Unrecognized parameter "td" -- ignored
The parameter "TD" is listed in the LTspice documentation in various places, and looks to be "transmission delay".
From the Help menu search:
Bipolar Transistor:
| Td | Forward excess-phase delay time | Sec | 0. |
A. Special Functions
The propagation delay defaults to zero and is set with instance parameter Td. Input hold time is equal to the propagation delay.
T. Lossless Transmission Line
Symbol Name: TLINE
Syntax: Txxx L+ L- R+ R- Zo=<value> Td=<value>
L+ and L- are the nodes at one port. R+ and R- are the nodes for the other port. Zo is the characteristic impedance. The length of the line is given by the propagation delay Td.
....
and others.
