WEBENCH® Tools/TPS54335A: Failure for 90% duty simulation

Part Number:TPS54335A

Tool/software: WEBENCH® Design Tools

I simulated TPS54335A's Webench on below condition, but  failure and indicate "Calculated duty cycle exceeds limit" .

I think that TPS54335A Webench data have a bug because I tried Low fsw condition but same results, please confirm it.

If it was bug, please let me know about revision schedule.

・Vin： 13.2V～21V

・Vout： 12V

・Iout： 1.1A

【Additional information】

・When fsw is changed low value (100kHz, 500kHz, etc), results was the same (duty cycle exceeds limit).

・TPS54335A datasheet is described "Min off time： 0%"

・TPS54334 was simulate normally, I feel that TPS54334 and TPS54335A are near specification.

Best regards,

Satoshi
