Other Parts Discussed in Thread: PMP10344
Hi I made a design by using UCC28700 to make a 12VDC 0.5A output power supply from 120-480VAC input range. Could you help review for me?

Thank you for reply!
1) the input voltage range is 120VAC - 480VAC; output is 12VDC; max output current 0.7A
2) I refer WURTH`s 750817930 specs but made a change as I only need one secondary. attached both datasheets.
3) No I didn`t use design calculator tool. I refered a demo design I found online (PMP10344_REVC) attached as well. Do you have a calculator tool to suggest?
Thanks a lot!
It's frustrating... I entered the 120-480VAC on the page you sent me and then click <Open Design> button, then the WEBENCH would automatically change my input voltage spec to 120-480V DC... so it will pick a MOSFET with 700V. If I change the spec to 680VDC (DC voltage after rectifier of 480VAC), then the design came out without this controller UCC28700.
