Part Number: UCC28740
Other Parts Discussed in Thread: TPS92314

Hi Team,

 

We are looking for a suitable device/solution at the following conditions.

*Power factor request vale is mandatory.

 

[Our Conditions]

Input : 85VAC to 230VAC

Output: 5VDC / 1A(max)

Power factor: 0.7 to 0.9

 

Could you please let us know a suitable device/solutions and test report?

 

By the way, I found PMP6740 but conditions are different and Power factor is low.

We need test report like a PMP6740 for our conditions.

    Hello,

    The UCC28740 does not have a PFC function.  The TPS92314 does and it was designed for fly back controllers.  The following link will get you to the data sheet.

    If you have questions regarding how to use the TPS92314 please repost with TPS92314 in the title so the appropriate engineer can answer your questions.

    Thankyou for choosing TI, Regards,
