Hi team,

I use Webench to simulate customer's application but I have one question about duty cycle simulation result.

Please clarify which portion I missed!

condition 4.6V~5.5V input and 4Voutput.

Please see 5.05V input we got highest duty cycle and 4.6V input we got lowest duty cycle.

Please advise.

Thanks

Hi Paul,

It should be Webench error. Duty cycle should increase with Vin decreased.

Thanks for pointing out! We will report to corresponding team.
