We plan to use MP9488 in a buck topology and small form factor as:
Vin = 300-450V
Vout = 3.3V
Iout = 30mA max
For this, we have used the following parts:
R1 = 2.7K
R2 = 10K
D1/D2 = RFU02VSM6STR (600V/200mA/25ns)
C1=100uF/450V Alco
C2 = 10uF/10V Ceramic
C3 = 0.1uF/500V Ceramic
C4 = 2.2uF/16V Ceramic
C5 = 470pF/25V
L1 = 1mH/100mA
Please confirm if this looks ok.

Hi Gaurav,
It is ok.
And we can also send you some documentation Schematic, Layout, BOM for reference design if you need. You can fill out the MPS NOW Technical Support form. A member from the MPS NOW team will contact you within 24–36 hours about this request.
