Team,

Could you provide an Excel base calc. tool ?

Because Webench cannot be likely to deal with the following condition, while basically UCC28911 should cope with it...

Vin range = 41V - 265Vac

Vo = 5V

Io = 1A

よろしくお願いします。

Thanks and Regards,

Hi Kenji-san,

I have asked one of the engineers to look at this issue. Can you provide more details on what is the issue with webench ?

Regards

Peter

Hi, Peter-san

Thanks for the prompt reply.

In Webench, the condition/spec I wrote cannot be calculated, but in case of Io=0.5A, Webench worked.

Vin range = 41V - 265Vac
Vo = 5V
Io = 1A
