TPS54302: En pin requires Floating when buck IC PSpice simulation

Cherry Zhou

Part Number: TPS54302

Hi team,

En pin requires Floating when buck IC PSpice simulation. However, this causes PSpice to be incorrectly reported as follows:

How does PSpice set up Floating? Thanks.

Hi Cherry,

I will take over this case.

In my understanding, PSPICE model cannot support any pin floating in simulation. Unless the model designer specifically setting the pin can be float but that's additional work.

TPS54302 EN-pin has the internal pull-up, float the EN-pin will enable the device. You may connect EN-pin to high to make simulation work.

Let me know if you have further question.
