Using TINA-Ti 9.3 simulate TPS5410,Why the result is not correct?

  • User,

    There are several reasons why the circuit did not produce the results you wanted. First, you were only simulating for 1000nS, which means the device did not have time to do anything (try 10m). Next, the operating point is not found, so you will need to select Use or Zero initial conditions from the transient Window:

    Finally, The VF1 voltage pin is not connected:

    Once you correct all of these issues, the simulation runs correctly, producing 5V output. You can also tie NC1 and NC2 together to eliminate the ERC warnings. The model that you are running is the TPS5430, not the TPS5410.

    Here is the corrected file:
