TLV770: simulation model accuracy

Fulvio Parisi
Prodigy 40 points
Part Number: TLV770


Tool/software:

Dear,

I would like to know what is the accuracy of the TLV770 simulation model available on the website and if I can use is to cover all possible operative condition of my project.

In particular:

1) I need to add a long cable with inductive parasitic and I would simulate the load step response;

2) I would check the behavior at -40°C and +125°C

Is the SBVMA03.ZIP (64 KB) - PSpice Model reliable for this simulations?

Best regards,

Fulvio

    Hi Fulvio,

    The tlv770p_trans.lib model file included in SBVMA03.zip notes the following:

    * Model Usage Notes:
    *
    * 1. The following features have been modeled
    *      a. Start-up behaviour is modeled
    *      b. Line transients 
    *      c. Load transients
    *      d. Current Limit and current foldback is modeled
    *      e. PSRR is modeled only till 1st pole and 1st Zero (Model limitation)
    * 2. Quiescent current, noise characteristics and temperature effects are not modeled

    Best Regards,

    Alex Davis
