I have to design a Flyback SMPS (15v , 6A) output. NCP1217 is the control IC being used to regulate the output power.
-->I downloaded the ".lib" file for the spice model from ON Semiconductor's website for NCP1217.
-->Opened this in my LTSpice console.
-->Right clicked on the
".SUBCKT NCP1217 skip FB CS GND DRV VCC HV params: Fswitch=65k Conso=960u"
and generated a sybmbol for it.
-->Thereafter I made all the connections, using the above symbol and tried to simulate it. But LTSpice generated an error saying :- "Cant find definition of model "N971-KN-1-0-20R18" ".
Please tell me what is going wrong here ? Is it not possible to use entire third party IC's in LTSpice ?
Please refer the link below and have a look at NCP1217's library files. There are multiple ".SUBCKT" lines present here. Which one should I use ? (I am using a switching frequency of 65kHz).
Kindly download the ".lib" file from here.
