Slightly more precise:
"hey guys , does anybody have the layout of that PSU posted by our friend ravslanska?
Waiting for an answer."

hi all the ir2110 version smps based on luka schema works well . but i want to try out the ir2153 version because it has few components. speaking of few components detexaudio 1200smps has the least components but it is a hustle for me to coil 220 turns on the small former.

my high power version of ir2153 smps with protection based on microsim schematic any comments or ideas are highly welcomed

Have you thought about the delay in the protection circuit's, also I think with some small component changes you can simplify this design, the other is why the daughter card?, also use IGBT's junk the IRFP460's.The fsw is below 50kHz there are many low cost's IGBT's that can replace the 460's and the driver circuits can be simplified.Also the SG3525 can be used as a fixed frequency controller and provide higher fsw's,smaller magnetic components and has built in protection or better yet MC34025.My thought's only.I will post a design shortly.An after thought I would use a small house keeping supply for 24,12 volt supply because any short in you fan or aux circuit could cause a major failure in your main's supply.

Default Another IR2153 supply

Found this on net, check drive for FET'S simpler,protection looks solid,you can use your resistors in lower FET source if you like but what a power waste,current transformer best solution.
