12V SMPS driver change big AC power from 110V or 220V into small 12V DC, also circuit is good for LED strip light. Furthermore, in this DIY project we can make cheap and strong LED driver, which can power full 12V LED strip with 100 or 200 LEDs. Important points to follow: Here, Circuit uses […]
Power Supply Circuits
3V to 9V Dual Power Supply Circuit
The IC 555 works in an easy circuit that generates both positive and negative voltages from a single 3V source, such as two AA batteries; in addition, this circuit works well in a 3V to 9V dual power supply system. Moreover, IC 555 work as astable multivibrator in circuit and it make square wave again […]
Simple Voltage Follower Circuit using Op-amp IC 741
A Simple Voltage Follower Circuit using Op-amp IC 741 provides an output that matches the input; therefore, engineers also call it a buffer amplifier or a unity-gain amplifier. IC 741 op-amp is cheap and useful that is why so many people use it. Voltage follower has high input impedance and with low output impedance and […]
