PMP2614: PFC-flyback transformer calculaiton

Part Number: PMP2614
Other Parts Discussed in Thread: UCC28810

Hi All,

 I would like to design a PFC-flyback power supply, conditions are:

 Input voltage:85Vac to 265Vac,

 Output voltage and power: 220Vdc/100W

 I would like to refer PMP2614 documents for this design, but no more experiences in LED power supply. To avoid design mistake in design process, can i have your support in transformer calculation, such as transformer calculation, semiconductor selections... Really appreciated!
