unisolated AC-DC power supply promote

Hello,

Have you searched TI's reference designs?  You can find them at the following link.  You just need to enter your input and output power requirements.

In the 100W to 200W power range a PFC buck converter could work.  The UCC28910A buck PFC controller could work but you should go with a 60V output instead of a 200V output.  There is a 100W AC to DC buck PFC EVM that might work for your application.  It can be found at the following link. 

Regards,
