"Operating point not found" in a circuit with the TPS40210

"Operating point not found" in a circuit with the TPS40210

I built a circuit with the TPS40210 and the related components, now when I run the DC analysis, appears "operating point not found." What can I do about it? I have calculated the conditions of the components with an input voltage of 18 V.

    Anne,

    Can you tell us what software you are using? The circuit posting did not come through.

    If you are using TINA-TI and a transient model, I am wondering what you were hoping to see from a DC analysis.

    Thanks for any additional information you can provide.

    Britt

    Anne,

    Can you provide the .TSC file you are using (if you are using TINA-TI)? If you are not using TINA-TI, could you tell us what simulator you are using and provide a copy of the circuit you are trying to simulate?

    Britt
