You can make a smps with two outputs by putting two windings on the transformer.
One for 24 Volts and one for 5 Volts.
You can only regulate one of the outputs.
The other will follow the changes in the regulated one.
Hi dhooker,
Here is a circuit for PSU for 24V @ 1.5A and 5V @ 1A. It is made using TOP246 from TOP-GX series of flyback converter ICs from Power Integrations Co. of USA. I personally made this circuit and still it is working fine. You can try this circuit.
I have attached it and also uploaded it to ifile.it. Here is the link:
