AT and ATX PC computer supplies schematics On this page i collect the schematics of switching supplies for Computers (SMPS) ATX v 1.0, ATX v 2.0 and some AT, which i found on internet. I'm not the author. The author is noted usually directly in the schematic. Schematics of halfbridge ATX (AT) supplies with TL494, KA7500 ICs TL494 and KA7500 are equivalent. The letters of 494 can differ. Theese supplies use bipolar junction transistors (BJT) of NPN type.
