Dear Team,

Do we have AC to DC Fly back topology regulator chipset to support 230VAc to 5V@3.5-4A.

Kindly suggest the best suitable part.

Thanks & Regards,

Hi Vishal,

Thank you for reaching out.

UCC28911 has an internal FET and it is not possible to have 4A at the output.

I would suggest looking at other PSR controllers like UCC28710/30/00 etc.

Regards,

Harish

Dear Harish,

Thank you for response.

UCC28730 efficiency is more compare to UCC28710.

Do you have any reference design for 5V@4A?

Thanks & Regards,

Vishal

Hello Harish,

PMP15002 looks good.

Can you suggest L1 (common mode choke) and T1(Transformer) standard vendor best suitable parts ?

Thanks for your response.

Hi Vishal,

I think it would be better to contact Wurth electronics or coilcraft for the best magnetics components for the design based on the pmp design values.

Thank you
