STCMB1 based design

Hi,

I am trying to design a power supply Vout=100V, Pout=500W, Vin=110VAC using the STCMB1.

From the STCMB1 datasheet and the EVLCMB1-90WADP datasheet is not clear how the flyback and PFC transformers should be designed. In these documents, there is no guidelines on the selection of the components used.

Are there any design equations, tools or guidelines?

Although the eDesignSuite is very nice, it does not contains designs with the STCMB1. Moreover the design resources are very limited. The 

STCMB1 combines a PFC controller and a LLC controller. No HB LLC controller is included in the eDesignSuite.

This makes me wonder if I should spend more time on this IC or should I turn to others like the Texas Instruments UCC29950 which at least provides a design calculator spreadsheet...

Looking at the top of my screen says 'Win a 3D printer! Embedded World 2017 Contest' which requires  a 60 seconds video about why you love and trust our STM32!

Well...If it was about STCMB1...Definitely no trust. Definitely not recommended...

Hi, how did it go with the power supply design?
I'm designing a power supply with the same chip, but I'm having some problems.
