One of my friends asked. Can we build the switching dc power supply circuit with 2 transistor? The applications IC that Sometimes is difficult. A some number IC is hard to find. and very expensive. When considering Applications for some time. We do not need to use a high current. and have sufficient space to install circuits. The selection use the transistors. Therefore as an alternative to saving, and extremely value for money. How it works In Figure 1 it is design of the switching regulator, which is a step down dc converter converts the voltage from 15-20 volts to …

Today take Multiple Supply Switching regulator Circuit. Come to deposit friends keep see in rows think out it can give Voltage supply about 5V 10A and 12V 3.5A. In same circuit by the character of Switching Regulator at use integrated readymade circuit. Work the character Synchronization between IC L4970 and L4974A. When friends see circuit think use a little many equipments. A friend feeds power supply input 35V 10A min just one group can give voltage output follow want. By the L1 use 80 uH sizes and , L2 = 300uH. The detail is other , request friends , see …
Today I leads Switching supply computer Circuit. Come to give friends in see again. By this circuit has can to give electricity pressure 5V 15A,-5V 1A,12V 10A,-12V 1A and have can to give the electric power about 200W. I hope that this circuit may in rows checking meditation repairs a computer has of friends. By think use the integrated circuit number TL494 again. And still use the transistor power as well. May repair not difficult be lucky sir. Source : do not know the source. Related Links More Circuit about 12v voltage regulator More Circuit about 5 volt regulator More …
