Part Number: TPS568215

Hello,

How can I perform stability (Bode plot) analysis of TPS568215? I cannot find the menu "Bode Plot" in WEBENCH.

Best regards,

Unfortunately, there is no bode plot analysis in WEBENCH for this device. One way is to just measure on the EVM or you can run a load transient on the transient model located at https://www.ti.com/lit/zip/slvmbt9 and can use PSPICE for TI simulation tool for free to simulate this model.

Thanks,

Amod,

Can the transient model be used for stability (Bode plot) analysis? Or, is it OK that you run the simulation of my design on my behalf?

Best regards,

Hi Shinichi,

Transient model can be used to run a load transient simulation which can help gauge stability by checking the output voltage deviation and ringing. We only have the transient model for this part so that is the only way to currently gauge stability. As long as you follow datasheet guidelines, the design should be stable.

Thanks,
Amod
