#195 SDC2921 Most Common configuration as voltage mode PWM controller in maximum ATX power supplies
in this video i discussed layout of SDC2921 IC Most Common configuration as voltage mode PWM controller in maximum ATX power supplies, this microcircuit is basic component to generate different voltages in at or atx power supplies, it generates pulse width modulation and monitors the output of power supply for proper function. after watching this lesson we will able to"-
how to change increase decrease the output voltage of any PWM controller
how to bypass over voltage protection
how to disable feedback circuit
how to recover or repair a dead computer power supply or any atx which turn on and then OFF automatically

To watch ATX power supply with AT2005 IC https://youtu.be/T_HoBKYwRSE
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using SDC2921 IC which is PWM and intelligent power supply monitor. i shared my easiest and perfect troubleshooting techniques practical troubleshooting. smps concept and troubleshooting repairing or understanding repair switching mode power supply basics and working principle. how to troubleshoot input electromagnet induction filter, EMI, bridge rectifier and capacitor. we get 330 VDC at main capacitor. after hat the +330 volts are applied to standby power, which is SMPS and makes +5V SB, these stand by voltage are applied to motherboard which pull down the PS ON green wire to zero level, so the ENABLE OR REMOTE ON or CONTROL pin of #smps will go low that will enable pulse width modulation. and also i discussed smps basics. after watching this video you can capable to:-
