TNY268-Flyback Converter Design

[themaccabee]

Hi,

I want to design a flyback converter

Input DC voltage range is from 60V-180V DC
Out put voltage required is a single tap - 15V/0.8A

I was looking through the TNY ICs like TNY268 ..
can somebody provide me some help?

Regards
Steve.

Hi i ve gone through them...but they give the design equations for AC input or too high DC input ranges can any one have an idea to make it work in 60-160 DC voltage range btw i ve been reading the AN-23 from their site
Thanks.

Hi,
What about AC input of ca. 40--110VAC?
The calculationprogram/simulation from PI is really good & good to use! ...
