Hi ,

I am wondering if webench can use for design isolation power with more than one output voltage.

Now I am thinking about to design a flyback with 85 to 260 input range with following output

+15V@1A / REGULATION: 2%

+15V@0.3A / REGULATION: 8%

-15V@0.2A / REGULATION:8%

+24V@1A / REGULATION:8%

can UCC28711 meet this requirement and what should be concern when choosing the other parameter(resistor) when design system?

Thanks for your help.

Hi,

Thanks for your interest in TI. Webench does not presently have the capability for multiple outputs for AC/DC. That's a feature we hope to add in the future.

I have contacted an applications engineer though to see if we have any ref designs for your requirements.

Regards

John

Hi,

This reference design I'll be linking to uses the UCC28700, which is very similar to the UCC28711 but the high voltage startup FET is removed, to provide multiple isolated outputs like what you are looking for.
