ATX modding revisited
Part Scavenger, Sun Aug 20 2006, 03:53AMI was wanting to mox an old PSU so that it puts out 15V. This is the datasheet for the SMPS controller
, but I don't know what I should be doing instead. It's not the usual '494 equivalent. Where should I send the new volt reference? I tried sending it to Vfb, but it doesn't change anything at all.Re: ATX modding revisited

Have you been able to induce any voltage changes yet? If not try fidling with the resistors around vfb, comp and current sense until you get something. Sorry I can't be of more help, but I've only done mods on TL494s.
