I'm looking for HV 100W dc-dc converter

Hello?
I want to design for HV dc-dc converter using non-isolation application.
But, almost of iC applications have flyback and too large.
If I make circuit for 100W convert from 100~440V to appx. 120V(0.8A~1A), what can I use product?
Please suggest to me.
120V @ 1A is 120 watts, from 440VDC a fly-back can be made to do this, or a half bridge using 600V mosfets, since you have to have a magnetic component you may as well make it a transformer to lower the stresses on all the components, you can then link the negative if you wish to remove the isolation, for smallest size a resonant approach at 150kHz would be preferred.
