5V Switch Mode Power Supply using LM2674
In the typical power supply is used in chip LM2674 company National Semiconductor , for many years engaged in manufacturing and designing components for the pulse transformers. LM2674 can be used instead of a chip LM2671 . By choosing different versions of chips, you can collect the converter with a constant (3.3, 5 or 12V) or with an adjustable output voltage. The above scheme gives a current of 500 mA. (more…)
