Hello Brian,

In the product page under "Design tools and simulation" you can find the simulation model: TPS62420 PSpice Average Model, which shows the loop response of the device. You would need to install PSpice which is at the end of the section.

Below is the Print of the schematic page of the model with the default conditions and settings.

Hi Natalia,

Thanks a lot for your support.

They only need the simulation for a common use like Vin=5V Vout=3.3V.

Best Regards,

Hi Natalia,

Thanks a lot.

I have asked for customer's design as below:

If it is convenient to you, please help simulation as their design.

And if you think their design is too complex, you can give me a simulation only with the same Vin Vout and Iout.

Best Regards,

Brian

As a suggestion, for newer projects we recommend the newest version of this device, the TPS6244x-Q1 https://www.ti.com/product/TPS62442-Q1
