Analog control for a push pull converter

[Optimus_prime]

I have a push pull converter with mulptiple outputs and it is working well in open loop. I would like to close the loop by implementing voltage mode conrol. I wanted to use TL494 but the information there is inadequate. Is there any other chip I could use without going the digital route?

Hi,
Try SG3525.

There's also an application note out there. Can't seem to find it, but Google can help.
