Input Rectifier Voltage rating is too small.

I made a low power design wiht Pi 9.0 yesterday.The power's parameter are below:
INPUT: DC+48V
OUTPUT:DC+12V,6A
The PI device in this power is TOP271EG,and i received some warnings:
1.Input Rectifier Voltage rating is too small.
2.Input Rectifier current rating is too small.
3.Estimated clamp voltage is too high.
Is this schematic wrong?What should i do to make it work?
thanks.

Hi,
TOPSwitch-JX was designed to use in applications where input voltage range is from 85VAC to 265VAC.
For your application I would recommend you to use DPASwitch family device. I am giving you a link for one of the reference design here
