Hello! I am currently working on a design for a buck converter for a project. I am utilizing a LM3150 buck IC to step a Vin with a nominal voltage of 24V to 5V @ 12A.
I have used the TI Power Designer to generate a schematic based upon my requirements, shown below:
The resulting steady state waveform for the output voltage plotted in the Webench tool is shown below:
I decided to simulate the schematic in Pspice for TI. The schematic used and resulting output voltage is shown below:
Between the two simulations, there seems to be about a 2.5V difference in the resulting output voltage between the Pspice for TI and Webench simulations. Could the issue be the type of solver that the solvers use for their analysis or is it something im overlooking?
