Part Number: UCC28070
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hi,

1. in TINA TI transient model of UCC28070 CDR, RDM pins are not provided which is required for practically as it is included in application note, would the results will be different in simulation and practical due to the neglection of these pins???

2. i dont want to use the average model of the boost, instead i want to simulate the real hardware components of the boost due to which F_KHZ pin will be useless

3. how to get the exact ic model used in the application note ?

4. how to enter the Kp Ki values of my controller using IC, if you have any related doc or link regarding this then do pls share?

thanks

    Hello sushank,

    Questions regarding this model has come up several times in the past and have been answered in different posts. You can serach for those answers and you will find answeres to those questions. Basically since the model was developed for average model, several pins were needed to be added . Those pins  are not needed for transient nor are present in the actual IC.

    I am closing this ticked per above note.

    Kind Regards,

    Arash
