200W ATX PC Power Supply uses chip TL494
200W ATX PC Power Supply uses chip TL494This ability accumulation circuit uses chip TL494. Similar ambit is acclimated in the best ability food with achievement ability about 200W.Device use push-pull transistor ambit with adjustment of achievement voltage. Line voltage goes through ascribe clarify circuit (C1, R1, T1, C4, T5) to the arch rectifier. When voltage is switched from 230V to 115V,
