WEBENCH® Tools/TPS53315: ripple

ADARSHA A N
Prodigy 245 points
Part Number: TPS53315

Tool/software: WEBENCH® Design Tools

hi,

i am using TPS53315 in my design below are the few queries related to its simulation.

Please find the below ripple waveform, steady state simulation result of TPS53315 using WEBENCH design tool for 5V output.

 in that pk to pk ripple is more than 0.4% even though max ripple is set to 0.2% in config window.

 and output voltage is gradually decreasing in the ripple waveform, but WBENCH tool has limited its  time scale so i cant check it for more time period.

 And webench for TPS53315 is not having option to  export  TINA TI or PSPICE For TI to get the full  proper waveforms,  i don't have other simulation options please help me in this.

thanks and regards

Adarsha  A N
