i am trying to simulator LM5005 regulator circuit in TINA. I have designed as per reference circuit. Getting error

OPERATING POINT NOT FOUND

in help tab it was mentioned to Set Parameters in the Analysis menu. I dont know what i am missing.

ravinandan,

What kind of simulation are you running? If you are using a transient model, you will nee to run a transient simulation. A DC simulation with a transient model would not have any meaning. If you are getting the error with a transient simulation, please try using the initial conditions or zero initial conditions in the transient simulation window instead of the calculate DC bias point. Some of the transient models may not be used to calculate a DC bias point (depending on the model structure).

Dear Team

I am trying for in DC analysis--> calculate nodal voltage (not transient analysis), getting this error.

Dear Ravinandan,

As Britt mentioned, the transient analysis needs to be used to get the voltages and currents at various nodes in the circuit. The DC analysis will not work for this.
