12V 50W Switching Regulator by UC3844N

Posted on Feb 7, 2014

This is a simple low-cost 50W off-line switching power supply, which can be used for home projects or to learn operation of flyback converters. It can work over a universal AC line input range 90-264 VAC and provides a 12VDC output at more then 4A load. Line and load regulation is better then 0. 5%. The unit has overcurrent, overtemperature and ove
