    Hi Suresh,

    Here it is. I'm not sure why it is not on the product page. I ran the startup simulation and it looks identical to the encrypted version startup so I think it's the same one but unencrypted. 

    TPS7A6933.LIB

    Hi Nick,

    Thanks for sharing an unencrypted SPICE model. I am getting an error while using in simulation tool as like 
    [error] parser(error): x201.x1_comp_hys.c1 - \tps7a6933.lib:139: Can't interpret "/6.93" (11:46:00 AM May 06, 2022). Please do let me know, Any modification to be done in the SPICE model to make it work in simulation environment.

    Regards,

    Hi Suresh,

    I'm not sure, the model worked for me with no issues. Line 139 from the TPS7A6933.LIB file is the following:

    C1 out  0 { (td + 0.5*tt) / 6.93 }

    It is a simply division by 6.93 so I'm not sure why it is having problems. 

    Regards,

    Nick
