Jerry Zhao

Part Number: UCC28911

Hi team,

UCC28911's datasheet mentioned that the maximum power UCC28911 can support is 12w, shown as below. And my customer wants to know the maximum power of UCC28911 under 90℃ and no wind condition. Could you pls help to answer this question?

Wish you have a good day, looking forward to your reply.

Hello,

The design in an adapter would be 90 degree C ambient. To the maximum the UCC28911 could handle 7.5 W from 90-265V AC and 8 W if the input range is 175-265V AC.
