Hi I have simulated TPS54116QRTWTQ1 in WEBENCH and the output is not stabilizing at given voltage. As discussed with customer support they asked to raise request for unencrypted SPICE model in E2E forum. Kindly provide the same.

Hi Rajesh,

Could you please follow steps mentioned in below image to share the design for the condition in which issue mentioned above was observed?

Our experts will soon get back to you on unencrypted SPICE model.

Thanks and Regards,

Umayal

Hi Umayal,

PFB. Link of my design. The steady state is not settling at 1.35V.

Hi Rajesh,

The steady-state simulation results seems fine. Vout is settling to 1.345V (~1.35V). Note that Vout ripple is also small (~4mV) though it looks large because of y-axis scale.

Please find below snapshot of simulation result. There is small variation (as indicated by blue arrow). This could be due to SPICE simulation parameters and such a small variation is expected in SPICE simulators.

Kindly let us know in case of any queries.

Thanks & Regards,

Harish
