Hi,

can we reuse the EVM UCC29910AEVM-730 for the application:

Vin 90-260V

Vout 84V

Iout 4,7A (400 W)?

Alternatively, is there any ref design for this application?

UCC29910

    John,

    my customer wants to build a power supply with parameters:

    Vin 90-260V

    Vout 84V and Iout 4,7A (400 W).

    They plan to use UCC29910 for this application. In this case is it possible to reuse the available EVM UCC29910AEVM-730  just by changing the passive componants (based on the calculation)

    Alternatively, maybe you can advise a ref design for this application?

    I gave an answer to this a week ago.. 


    I said it was possibly, but be aware of the harmonics. At only 100W (EVM board)  the SMPS is near the limits of EN61000-3-2.

    So increasing the power, would properly make things worse.. But it's worth a try.
