    Hi,

    The model on ti.com is as is and correct.

    Your cited looks is for some other simulation compatible as mentioned ngspice.

    The model has been used as is and has been ok. 

    If you use the model with TI suggested simulation software and you find the result is different from the device datasheet specs please make specific so we can take a look,

    Otherwise we cannot help on the model transfer to other simulation softwares.

    Hello Hong:

    Appreciate your review & comments on the UC3825 model.

    I mis-judged the model after I used in TINATI.

    If I apply the exact same circuit that old Unitrode AN_110 had, it works to reproduce results in AN110.

    So it was my fault not to have used a known circuit to evaluate the model.

    Issues closed.

    thnx
