WEBENCH® Tools/TPS53315: Simulated output mismatch

Part Number: TPS53315

Tool/software: WEBENCH® Design Tools

Hi,

I am using the regulator TPS53315RGFT (12A) in my design for the following outputs;

1) 1V @ 9A

2) 1V @ 9A

3) 1V @ 10A

4) 1.8V @ 9A

5) 3.3V @ 5A

I simulated the design with different output configuration in WEBENCH and in all cases simulated waveform was incorrect as per expectation.

I have also used other regulators in my design and the WEBENCH tool simulated proper output waveform as expected.

I have attached one of the case's report obtained after simulation.1V0_9A.pdf

Please let me know the reason of such issue ASAP.

Thanks and Regards,
