SN6501 isolation transformer for 10 V

Hi all,

I need a isolated dual power supply max 40 mA. I would like to use basic configuration with wurth midcom transformer type 760390015. The transformer selected works with 3.3V primary input, the ratio is 1:2.1, and output is 6.9 V
Can I replace the 3.3V with the 5 V (input side) so i will have 10.5 V (x2.1) ?

thanks.
