LTSpice model is missing pins?

Hi,

I posted yesterday in regards to controlling my HV buck regulator, and was suggested to use LTM9100. Since I needed to sense the current and have knowledge of the output voltage that needed regulating, I found an appropriate application in the data sheet.

However, when inserting the model into my LTSpice file, some pins (some essential pins) are completely missing. I have attached a screen grab of the circuit I wish to use, and the LTSpice model. You can see that the sense- pin is missing (Only the sense+ exists) and furthermore, the ADIN pins are missing (there should be more than 1 - there are 0 in the schematic!)

Anyone had this issue before with LTSpice?

Hi

Sometimes certain functions are not simulated and therefore the associated pins are not available in those devices.

check with Analog.com support.
