NEED HELP ON BUCK CONVERTER FROM 170v-450v INPUT TO 12V 300mA OUTPUT

Dear PI,
we are looking for a solution to convert a rectified three-phase voltage with range 170Vdc-450Vdc to a 12V - 300mA output.
We prefer to find a non isolated solution since it's not required by the application. However we can also evaluate an isolated solution.
Thanks for your help.
for isolated solution, you can consider use LNK-TN2 as buck topology. examples are

an design example, there are a few other designs available as well on the website

if you consider an flyback topology, you could consider LNK-XT2
