LT3999, multi secondary output

Hi, 

I agree with Alex comments. You might need a customized transformer. LTspice is a good tool to use to verify the ratios. 

However, please note that LT3999 is not a regulator. It is basically running with open-loop. The duty-cycle may change with VIN, but it will not respond to any change in load current as it does not have a feedback loop. 

Thanks,

Wenwei.
