Here in this video you will watch a review of a power supply which I have received from one of my subscriber. Switching power supplies or smps are very common type of power supplies now a days. smps or switch mode power supply is everywhere. In all equipment smps is used as standard power supply today. Switch mode power supply or smps has common failures and defects. Acquiring smps repairing could be a useful skill. Every electronics and electrical person must have ability to repair such kind of smps power supply. smps power supply is common for atx power supplies also. computer atx power supplies uses more than two power supplies in them which are smps or switch mode in nature. Hope this video will give enough understanding to viewers to understand smps or switching regulator used in cellphone chargers and in camera chargers and adapters. Next laptop charger power supply repair video would come soon.

Hmm a better design, the output voltage is monitored by a TL431 or similar shunt regulator and some resistors, it drives the led side of the opto coupler and the opto coupler output feeds back to the pwm flyback i.c. Much better accuracy :-D The output schokky diodes look overloaded by someone being too greedy for power lol. Maybe 1.5 amp output current.
