ATX 2005 POWER SUPPLY PWM SUPERVISOR Power Supply Pulse Width Modulation Integrated Circuit Controller Specs (English version) version 1.0 April, 2012 Original chinese document downloaded from: http://www.4shared.com/office/_E8A5czR/ATX_2005.html Free Datasheet http://www.Datasheet4U.com ATX 2005 Specification: v-1.0 Page 02 General Description The integrated circuit ATX-2005 is a pulse width modulation (PWM) controller, which can be used in the power supplies' secondary side, ready to provide the total voltage and load switching control. ATX-2005 has all inside functions for protection and control, undervoltage/overvoltage detection, output voltage status monitor (PG), external remote control (REM)... and more. The ATX-2005 is able to set the power supply's behavior in order to reduce the external devices usage to get required control. The undervoltage (UVP) and overvoltage (OVP) modules assist the 3.3V, 5V, and 12V voltage levels. The PP function is set to monitor power and negative voltages, and a built-in shunt regulator module (the 431 shunt regulator) is built to make the PWM's correct level control, providing a stable output voltage through a group of amplifiers that monitor the feedback pattern. Besides, the antinoise filter prevents malfunction caused by outer interference. Features 3.3V / 5V e 12V Overvoltage Protection 3.3V / 5V / 12V Undervoltage Protection 3.3V / 5V / 12...
