Dear Sswalia.

Thank you for reaching out to us.

Nowadays Power Integration TOPSwitch devices are highly optimized to work with flyback topology to obtain the highest efficiency available in the market. When PIexpert ver. 4 was released (2004) the control techniques used in the IC were rawer and less sophisticated and could easily be adapted to work in conjunction with other topologies (within limits).

I would strongly recommend you to consider utilizing a flyback topology for your application.
You can contact the PI sale representatives in your area if you need any in-depth guidance on how to select the best PI product for your application.

If you have any other question or comment please do not hesitate to contact us.

Best regards.
