Greetings all,
This is my first time playing with active power factor correction (APFC) IC.
With parametric searching at Element14, I found that FAN7527BN is the cheapest among all.
Doing my homework on the net, I decided to try to build one for myself. Here are the references.

My curiosity is inhibited by the use of smps transformer with specific characteristic required by the IC; which is hard to get by me.
I really prefer to use just an inductor as the energy storage device, and separated power transformer for the IC supply.
I don't mind if changing the IC is required, as long as the circuit is simple enough for me to comprehend, possibly, doesn't cost too much.
Any advice? Thanks.
