Hi, I designed a step-down converting circuit. I was able to get the simulation working but then I added a shunt resistor and the TSC101c currenst sensing amplifier and I get a convergence simulation issue. I tried the TSC101c model in an other circuit and it worked fine. Thank you for the help...
Thank you very much! What if I want the steady state solution? If I raise the run to time value it gives me back the same convergence error. Moreover I would expect to have a voltage value of 5V where I put the marker (see image) instead, after 1.0us I have 3.8mV
I made some changes in the values of the capacitors, because I found out they were wrong, but still have the convergence issue. I've attached the entire archive of my project below.
There you can download the TPS54331 Pspice model that I used:
Hi, I'm developing a step down converting circuit using the Texas Instrument Converter TPS54331. I imported the PSpice model of the component and draw the circuit, but when i launch the simulation the sequent error appears: ERROR -- Convergence problem in bias point calculation
