Part Number: LM3481-Q1
Tool/software: WEBENCH® Design Tools
Hello ,
I'm using the LTspice XVII to simulate a SEPIC circuit , the LM3481 PSice model which I download is LM3481 Unencrypted PSpice Transient Model (Rev. D) , when I start the simulation , it shows a notes like below,and the simulation couldn't work , the u1 is LM3481 in my circuit , and the SEPIC circuit is connect well , I don't know what's the problem of this model , could you help me to check it ? thanks !
I copy the error log below :
