You can use the transient model at https://www.ti.com/lit/zip/slvmcf6 to do this simulation. Please download the free simulator https://www.ti.com/tool/PSPICE-FOR-TI and then unzip the model and run the sims.

Thanks,

Hi Ramakrishna,

Please see attached load transient testbench. Under startup -> page 1 schematic, you will see the schematic. You can edit the components to your requirements and also if required, please update the IPULSE current source specifications to change load step parameters.

Once done, click PSPICE and click run to see simulation results.
